Summary

Mercedes-Benz C-Class

Do you know how many bones you have in your body? Stop counting, there are 207. And if say half those bones were replaced with different ones would you consider yourself to still be the same? Well that’s what Benz has done with the new C-Class – sort of. Of the roughly 13,000 parts which make up a C-Class car, 6500 of them have been modified or changed.

You don’t need to know every change to the new C-Class, but at the end of this review you will be across the differences that you can see, feel and hear.

Just a note before we start. The top-of-the-range Mercedes-AMG C63 S arrives in early 2019 and wasn’t available to drive at the Australian C-Class launch. That’s why we’ll focus on the other grades here - the C 200, C 220 d, C 300 and C 43. We’ll test drive and review the Australian C 63 S when it arrives – promise.

BMW Z4

I remember the first Bond film I ever watched.

I was about eight or nine years old, and it was GoldenEye on VHS. In that film, Pierce Brosnan drove a BMW Z3 convertible, which obviously oozed cool.

I didn’t know at the time that it was just a little bit weird that he wasn’t driving an Aston Martin for the entire duration of the movie, but it didn’t matter, that drop-top Beamer with its radar and missiles imprinted itself on my mind.

As such, I’ve always had a soft spot for BMW’s 'zed' range, so I was quite keen to helm this new one as it came through the CarsGuide office, especially since it shares its underpinnings with the new Toyota Supra.

So, is the new Z4 a case of never meet your heroes? Or did it make me feel a little bit like a secret agent? Read on to find out.

Verdict

Mercedes-Benz C-Class7.9/10

This may well be just an update to the C-Class, but the changes made are significant in terms of technology and performance, and you’re paying hardly any extra money for it. A good all-rounder for dynamics, features, refinement and value.

The sweet spot in the range has to be the C 300. It’s less than $10K more than the entry grade C200, but gets a powerful 2.0-litre engine, leather seats, the extra advanced safety equipment, tinted windows and convenience features such as a power tailgate (on the wagon) and proximity unlocking.

Is the C-Class still the king of the mid-sized prestige world? Tell us what you think in the comments below.


BMW Z47.5/10

The Z4 didn’t make me feel like Peirce Brosnan’s 007. It’s way too serious – a proper gritty reboot. Maybe it’s meant for Daniel Craig. Either way, its brave design makes it one of the best-looking BMWs of recent memory, and it’s a tech- and comfort-fest that the Bavarian automaker should be proud of. I just wish it was a smidge more fun behind the wheel.

What do you make of the Z4’s looks - Is it an icon or too far from BMW’s roots? Share your thoughts in the comments below.

Design

Mercedes-Benz C-Class8/10

Now, to spot the difference between the new and the old C-Class from the outside just look at the headlights – the shape of the fitting is the same, but the new standard headlights on the C 200, C 220 d and C 300 have an LED set-up which looks like teeth, while the optional units (standard on the C 43 and C 63 S) are also LED but with a tall staggered design. Tail-lights also keep the same shape but with a different LED pattern, too.

The front and rear bumpers have also been restyled for all grades and the C 43 and C 63 S have had their grilles updated, with the former getting a new twin-louvre design, while its big brother now has chrome vertical slats reminiscent of the grille worn by the 1952 Carrera Panamericana winning 300SL.

The AMG Line Exterior package is standard on the Coupe and Cabriolet, but if you option it on the sedan it will fit a sports body kit with AMG front spoiler and side skirts.

The C 43’s gloss black rear diffuser looks tough with the new quad exhaust and the car in wagon form wins my award for best looking of the C-Class bunch.

Cabins haven’t been overhauled but they have been updated with a 10.25-inch dash-top display for media and a 12.3-inch fully digital instrument cluster - both are standard across the range and make a big styling impact in the cockpit. Mercedes-AMG grades have their own sporty version of the virtual instrument cluster.

The layout of controls remains the same, but you can now option a new real wood veneer to the centre console with 'open-pore brown walnut' and 'open-pore black ash' being your choices.

The Artico upholstery in the C 200 looks and feels ‘plasticky’. I’d option the real leather which comes standard on the C 300.

New to the C 43 are the optional ‘Performance’ seats with integrated head restraints and standard on this grade is a new leather AMG steering wheel. Other cool cabin features are the stainless-steel pedals, the AMG floor mats and stitched dash (even if it is Artico upholstery).

All grades now come standard with the 64-colour ambient lighting system. You should see the system fading through the colours at night and with the right music the whole effect is amazing.

The C-Class comes in four body styles: Sedan, Coupe, Estate (wagon) and Cabriolet.

Exterior and interior dimensions stay the same, all variants measuring about 4.7m in length. That’s a good size; not too big or small, making parking and manoeuvring in tight spaces pretty fuss-free.

The C-Class is made in various parts of the world, but I can tell you the C 200 Sedan we get in Australia is made at Mercedes-Benz's East London plant on South Africa's east coast.


BMW Z48/10

The Z4 is a sight to behold. It’s brave, especially for a BMW, it even betrays the brand’s strongest styling pillars, making its own way with its more horizontal grille design, flat body and curved out rear.

It’s more than that, though. In black, this car looks sinister, brooding. The more you look at it, the more you notice tiny details - the scooped-out sides, or the way the entire rear seems to flick up into the integrated spoiler. I couldn’t get enough of staring at it – it manages to look even better with the roof down.

That’s probably when it hit me. To my eyes, at least, this is the most stunning BMW in years. Sure, the X7 is a sight to behold due to its sheer dimensions and borderline offensive grille, but the Z4 is the opposite. It’s subtle, it hides its details away in its silhouette.

It’s designer, Calvin Luk (an Australian no less), was inspired at least in part by the Z8 – another Brosnan bond car – and you can see the Fisker design reflected in the Z4’s low, flat grille and almost bulbous rear.

Inside, sadly, the Z4’s strong design doesn’t quite play out. There’s no wily Fisker touches here, just a standard set of BMW switchgear. While it all works well, it just dumbs down the Z4’s character.

The big, chunky steering wheel in particular is a let-down. It’s the same wheel that sits in the brand’s X5 SUV, and it feels right there, but not here in a convertible where you’re so close to the ground. A smaller wheel would not only suit this car better, it would make it feel just a smidge more alive. I miss the three-spoke M sport wheel from previous-generation BMW cars.

I do like the dash, which is seemly carved from rhomboid shapes - a theme that rolls into the doors, screens, and vents elegantly. I’m normally not a fan of gloss plastics and chrome touches, but in the Z4 they’re all tastefully applied.

The seats, too, are lovely. I’m not sure about the contrast bright-red leather our car came with, but they’re nice and close to the ground and have excellent trim that you seem to sink into just enough to be comfortable and sporty all at once.

It’s a slick place to be, I just wish it felt less like you were at the helm of an SUV and more like you were driving something that looks this damn good.

Practicality

Mercedes-Benz C-Class7/10

This depends on the body style, but being a mid-sized car practicality can be limited, but Mercedes-Benz has been clever with the way it has used the available space.

The boot, for example in the C 200 is 434 litres, which isn’t as big as the cargo space offered by the BMW 3 Series or the luggage capacity of the Audi A4. This is partly because the hybrid system uses space under the bonnet, so the car’s battery needs to go to the boot.

The C 300 doesn’t use the hybrid system and so the sedan in this grade has 455 litres of boot space.

Choosing the C 300 Coupe’s will reduce your luggage carrying ability to 380 litres and the C 300 Cabriolet’s cargo capacity varies from 360 litres with the roof up and 285 litres when it’s down and eating into the luggage area.

The Estate is the best luggage hauler but it’s still not enormous – the C 43 Estate that we test drove has a cargo capacity of 480 litres.

Legroom in the back of the C 43 Estate is good and at 191cm tall I can sit behind my driving position with about 20mm to spare thanks to the sculpted seat back.

Headroom is getting tight in the Estate and especially in the Sedan – well for me, anyway – and the optional sunroof will lower the ceiling height even further.

Up front space in the Sedan and Estate isn’t an issue with plenty of head-, leg- and shoulder room offered.

Storage throughout the Sedan and Estate is good with a large centre console storage bin, two cupholders up front and another two in the back along with a storage area in the fold down armrest, but all four door pockets are on the slimmer side. Still they can fit a small bottle of water, plus a wallet or purse.

That centre console bin houses two USB ports, and a 12-volt outlet can be found in the storage area under the climate controls – which also houses the optional wireless charging pad. Without the charging pad that small area is too tiny to place my iPhone8 Plus.

Rear headroom and legroom in the four-seater Coupe and Cabriolet is limited, but both get a pair of cupholders in the back and two more up front.


BMW Z48/10

The Z4 is a convertible, so it’s naturally compromised on space. As far as convertibles go though, you’ll be hard pressed to find one you can fit more stuff into.

The Z4 is wide - the same width, in fact, as a 5 Series - and this carries into the cabin. There are only two seats, but those seats are wide, and occupants will find themselves with luxurious amounts of airspace for their arms, as well as excellent leather-trimmed and padded surfaces for landing elbows on.

Legroom is also great, as the seats have a surprising amount of rail-travel on them, so that even taller folk won’t struggle to fit their limbs in.

A genuinely impressive characteristic of the Z4 is much head room there it is. Despite its low-slung looks from the outside, the roof towers over my 182cm tall head when I’m inside, so this isn’t one of those convertibles that feels like braking too hard might simply decapitate those above six-foot tall.

In terms of storage areas you get some long but shallow trenches in the doors, a bay with connection ports and a Qi wireless charging pad under the air-conditioning controls, a glovebox (hey, not all convertibles have them) and a trick centre console that houses two deep cupholders inside.

There’s also a netted shelf behind the seats that could fit small bags, and given the length of the cabin, you could even fit laptops and the like behind the seats provided you haven’t used the full extent of the seat’s rearward movement.

The boot is deep, wide and long for a drop-top, and offers a total of 281-litres which is more than some popular hatchbacks. It even offers tie-down points and netting either side. To top it off, the fabric roof folds away into its own compartment, so the boot space is unaffected if you choose to drop the lid.

For a convertible – the Z4 is a practicality wizard.

Price and features

Mercedes-Benz C-Class8/10

The range kicks off with the C 200 and its C 220 d diesel siblings, then steps up to the C 300. Prices for these grades have increased by $1500 in this update but you’re being given more features. Above the C 300 live Mercedes-AMG’s wild animals – the C 43 and C 63 S.

The C 200 Sedan now lists for $63,400 (plus on-road costs), and if you want the Estate version add another $2500, and an extra $4500 for the Coupe, while the Cabriolet is $25,000 more at $88,400.

The C 220 d Sedan lists for $64,900 and the only other form it comes in is the Estate for $67,400.

The C 300 Sedan lists for $71,400, the Estate is $73,900, the Coupe is $84,900 and the Cabriolet is $101,900.

The C 43 Sedan lists for $107,900, while the Estate is $110,400, the Coupe is $111,900 and Cabriolet is $124,900.

The C 63 S Sedan lists for $159,900, however, prices for other body styles have not yet been announced.

So, about all the stuff you’re receiving in return for the price increase – a 10.25-inch display screen replaces the smaller one in the previous car and it’s standard across the range. Don’t stab and poke at it like I did with my finger for hours, because it’s not a touchscreen.

Also new is the 12.3-inch fully digital instrument cluster, and it’s standard on all grades, too. Apple CarPlay and Android Auto come on all C-Class cars.

Other standard features, starting with the C 200 and C 220 d, include 'Artico' upholstery, which is a synthetic attempt at leather, a reversing camera, shifting paddles, dual-zone climate control, aluminium roof rails on the Estate, LED headlights, 64-colour ambient lighting and 18-inch alloy wheels.

The C 300 has the C 200’s features and adds leather upholstery, privacy glass (coupe only), proximity key and 19-inch alloys. The C 300 also gains the 'Driving Assistance Package' which I’ll tell you all about in the safety section below.

The C 43 picks up the C 300’s equipment and adds an enormous list of its own gear including a new AMG steering wheel, brushed stainless steel pedals, Burmester 13-speaker stereo, heated sports front seats, head-up display, wireless charging, intelligent LED headlights, panoramic sunroof, black roof racks on the Estate, analogue clock and 19-inch AMG alloy wheels.

Metallic paintwork is also part of the C 43’s standard features list which includes 'Obsidian Black', 'Iridium Silver', 'Mojave Silver', 'Cavansite Blue', 'Emerald Green' and 'Brilliant Blue', but you’ll have to pay for 'Hyacinth Red', which is a sort of candy apple red. Non-cost colours for the lower grades are non-metallic black and 'Polar White' non-metallic.

The C 63 S adds to the C 43’s equipment list with its own AMG steering wheel, illuminated door sills, digital TV tuner, nappa leather upholstery, an electronic rear differential lock, 19-inch alloys in matte black with high-sheen rim, plus high-performance brakes with red calipers.


BMW Z47/10

The Z4 isn’t cheap, but it plays in a field of expensive Deutsche drop-tops. Our car was the mid-spec 30i which comes in at an MSRP of $104,900 (before on-road costs).

For that you’ll get a more highly tuned version of the base 20i’s four-cylinder turbocharged engine, producing 190kW/400Nm, 19-inch alloy wheels, M Sport brakes, Adaptive M suspension, and adaptive LED headlights.

That’s on top of the already impressively-specified 20i’s kit which includes dual 10.25-inch screens – one for the multimedia functions, the other as a digital dashboard, a head-up display, full Vernasca leather interior trim, auto-dimming rearview mirror, power adjustable and heated front seats with memory function, dual-zone climate control, 10-speaker 205W stereo, a Qi wireless charging pad, and adaptive cruise control as part of a marginally upgraded safety package (more on that in the safety section).

It’s a pretty plush set of equipment, although a challenging value proposition as the almost-as-well-equipped 20i starts from $84,900, a full $20k cheaper.

Rivals for this 30i model? You’ve got the soon-to-be-discontinued Mercedes-Benz SLC300 ($102,500), all-wheel drive Audi TT S quattro ($105,661), and, at a stretch, the entry-level Porsche Boxster ($122,960).

Of course, being a premium European car, there is an extensive options list. Our car was fitted with the excellent and probably-worth-the-money M Sport differential ($2400), as well as the rudely priced M seat belts (literally just the M pattern embroidered in - $560!) and interior ambient lighting package (lovely, perhaps not worth $550).

The Z4 is only offered in five colours, three of which – including our car’s Black Sapphire – come at a cost of $2000. The red interior, surprisingly, is a no-cost option.

If you’re keeping track that brings the car you’re looking at here to $110,410. Not cheap, and it doesn’t have six-cylinders - but given its other attributes explored later in this review, the fact that it still manages to undercut an entry-level Boxster is actually reasonable.

Engine & trans

Mercedes-Benz C-Class9/10

The previous C 200’s 2.0-litre 135kW/300Nm four-cylinder petrol engine has been swapped for a 135kW/280Nm 1.5-litre four-cylinder turbo-petrol with what Benz calls a ‘mild hybrid’ function.

This isn’t a hybrid with an electric motor driving the wheels, it’s an electrical system which is able to provide an additional 10kW/160Nm when accelerating. Known as the 'EQ Boost', the system also allows the C 200 to coast at a constant speed if the driver takes their foot off the accelerator. The battery is then re-charged when braking.

The C 220 d offers a diesel alternative and its new 2.0-litre engine now makes 18kW more power at 143kW and the same 400Nm of torque.

The C 300’s 2.0-litre turbo four has had a 10kW increase, taking power to 190kW, while peak torque is still 370Nm.

Also getting a power bump is the C 43 and its 3.0-litre V6 petrol is now good for 287kW (up from 270kW) while torque stays at 520Nm. The C43 uses Mercedes-Benz’s '4Matic' all-wheel drive system, while every other grade, including the C 63 S, is rear-wheel drive.

The C 63 S still makes an impressive 375kW and 700Nm.

The C 200, C 220 d, C 300 and C 43 all use the same nine-speed automatic transmission, while the C 63 S uses a ‘AMG Speedshift 9G’ which is a nine-speed dual-clutch auto.


BMW Z48/10

Welcome to the age of ridiculously powered four-cylinder turbo engines. Despite a capacity of just 2.0-litres, the engine in the Z4 30i produces a whopping 190kW/400Nm.

That’s probably enough for a car this size. I’m keen to drive the six-cylinder, but surprisingly it seems to offer diminishing returns for extra cylinders offering a 60kW/100Nm power boost for an extra $20,000. Perhaps a six-cylinder is the way to go in a BMW, and given this car’s other seriously sporty attributes, it might be the only way to make it a bit more… fun. More on that in the driving section.

All Z4s are rear-wheel drive, using an eight-speed torque converter automatic. Sorry, no option for a manual this time around.

Fuel consumption

Mercedes-Benz C-Class8/10

Fuel consumption obviously depends on the engine, but did you know the body type also affects mileage?

Mercedes-Benz says the C 200 Sedan uses 6.4L/100km over a combination of open and urban roads. The trip computer in our C 200 Sedan recorded 7.1L/100km after 254km of mainly country roads.

The C 200 Estate according to Mercedes-Benz will need 6.5L/100km, the C 200 Coupe uses 6.4L/100km and the C 200 Cabriolet will need 6.8L/100km.

The C 220 d Sedan is frugal with diesel fuel consumption being 4.7L/100km, while the Estate version needs 4.8L/100km.

Mercedes-Benz is yet to announce the C300’s fuel consumption figures.

The Mercedes-AMG cars are the thirstiest with the C 43 Sedan using 9.4L/100km, and the Estate will use 9.6L/100km. After 286km of country roads the trip computer in our C 43 Estate was reporting an average consumption of 10.3L/100km. The Coupe economy is 9.5L/100km and the Cabriolet needs 10.0L/100km.
 
The C 63 S Sedan puts it away at the rate of 10.4L/100km, and the Estate’s usage is 10.7L/100km, while the Coupe and Cabriolet’s fuel efficiency is yet to be announced.


BMW Z47/10

It’s claimed that the Z4 will drink just 6.5 litres per 100 kilometres on the official combined cycle test, but I found that sticking my foot in occasionally resulted in a slightly more realistic sounding figure of 8.4L/100km.

That’s still a great fuel consumption number for a car like this, and perhaps one of the strongest benefits of having just four cylinders.

A discerning vehicle, the Z4 will drink nothing less than the best-quality 98RON unleaded to fill its 52-litre tank.

Driving

Mercedes-Benz C-Class8/10

The Australian C-Class launch gave us the opportunity to drive the C 200 Sedan and C 43 Estate on a test route stretching from Melbourne's Tullamarine airport, roughly 300km north to Milawa in Victoria’s alpine region and back, with the conditions being dry and cool.

I knew the C 43 would be ridiculously fun, but you can’t eat your dessert first, right? So, I started in the C 200, which is far from just meat and three veg – it’s refined and enjoyable to drive.

Steering is well weighted and accurate, offering a better sense of connection to the road compared to some of its prestige rivals. The steering wheel itself felt good to hold, too – and this is on the base car.

The test car wasn’t without its options though and it did have the 'Dynamic Body Control Suspension' with its Comfort mode softening the dampers for a more compliant ride and the Sport setting for better handling.

And that ride was comfortable. The only disturbance to the serenity (we did go through Bonnie Doon) was a bit of wind noise created by what sounded like the wing mirrors.

Apart from that, the experience was serene – those seats up front are comfortable and supportive even after hours, the vision all-around is excellent and then there’s the engine, which is perfectly adequate.

Okay, 1.5 litres sounds small but the output is almost the same as the previous 2.0-litre and the 48 Volt EQ Boost hybrid system does provide just enough of a kick to get you away from the traffic lights or overtake without any discernible lag.

The hybrid system's coasting function is excellent – take your foot off the accelerator and your revs drop to zero but the car will maintain its speed. When you brake the battery is recharged so you’ll have the extra grunt again when you need it.

Now for dessert. Just idling the C 43 sounds sedate, but that’s with the exhaust note and engine in the Comfort setting. It means you can pull into your street at night or start it up early in the morning without waking the up the entire neighbourhood.

Or, to hell with them, the people next door are jerks anyway: put it in Sport and the twin-turbo petrol V6 snarls and crackles as you shift through the gears. It’s not as vicious as the V8 C 63 S, but that’s the appeal of the C 43 – it’s a milder form of wild that’s easier to live with, but still so much fun.

The back roads from Milawa to Mansfield were a great testing ground for the C 43 Estate with their hill-climbing bends and downward forest runs. Merc AMG claims the C 43 can accelerate from 0-100km/h in 4.7s, and while that’s more than half-a-second behind the C 63 S, it’s still plenty quick.

With fantastic turn-in, all-wheel drive offering superb traction and great grip from the Continental ContiSportContact rubber (225/40 R19s front, 255/35 R19 at the back), a smooth-shifting nine-speed, impressive brakes and that turbo V6 which pulled the car heroically out of corners, it was hard not to grin like an idiot.

Only my mouth hurt afterwards, not my body. There’s a line you’re not going to read in any other car review. Some sports cars have a ride so firm, and seats so hard, and driving positions with hip points so low, that I almost have to leave the vehicle on all fours.

But only my face hurt from smiling so much – you could pilot a car like the C 43 until it ran out of fuel from a full tank and still feel comfortable – which is almost what we did. How much fuel did it use? Keep reading to find out.


BMW Z48/10

A car that looks this good better live up to the promise behind the wheel, right?

For the most part, the 30i does, but it’s a victim of its own performance credentials and luxuriousness.

See, a drop-top should be fun-packed, you should feel close to the road, connected. Sadly, a combination Z4’s excellent suspension and not-so-excellent SUV-like interior separates you too much from the surface below.

An advantage, of course, is the refinement on offer. The Z4 is easily one of the quietest, most refined convertibles I’ve ever driven, but it’s a little too insulated.

I can’t help but feel like it’s all business and no pleasure. It feels a little more like I should be cruising to work on the autobahn and a little less like I should be flinging it around corners on a tight B-road.

It feels almost wrong to drive it in a T-shirt. It’s serious and doesn’t want you to mess around, it wants you to wear a suit and tie.

This grand-tourer style feel is one that will keep a lot of buyers in the premium space happy, but I’m of the opinion that BMW will have that segment well and truly covered by the new 8 Series. If the budget allows.

Regardless, the 30i’s four-cyl engine feels like any six-cylinder would have a few years ago. It’s got a surge to it in the straights that’s quite satisfying, and it responds via the exhaust with an angry tone that makes it feel a little more alive, especially with the roof down.

This feeling was all helped along by our car’s M active differential which simply won’t let the fat tyres at the rear slide unless you’ve got high-speeds and loads of tarmac to play with – for better or worse.

The Z4 also has ‘variable sport steering’ which reacts to the car’s speed and position of the wheels to adjust the input ratio. It’s good when you’re at speed, but the weight and response of the steering can make the Z4 feel bigger than it actually is at lower speeds. 

The suspension is firm, and can be a little bouncy over rough surfaces, but seems well suited to the Z4’s chassis.

Other than those notable characteristics you’ll find that the Z4 is wonderfully tuned in terms of its inputs, everything is slick and smooth, suited perfectly for long meandering drives.

Safety

Mercedes-Benz C-Class8/10

The C-Class was awarded the maximum five-star ANCAP rating when it was tested in 2014. The base grade C 200 is fitted with nine airbags, AEB which works most effectively at lower speeds, and blind spot warning.

Stepping up to the C 300 brings the 'Driving Assistance package' which adds a more sophisticated AEB with cross traffic function and evasive steering, plus lane keeping assistance.

No spare tyres here. The C 200, C 220 d and C 300 all come with run-flat tyres, while the Mercedes-AMG grades have a puncture repair kit.

For child seats, you’ll find two ISOFIX points and three top tethers across the back row of the Sedan and Estates, while the Cabriolet and Coupe have two ISOFIX points in the back.

There are also two hi-viz vests in the cargo area and, yes, you do get a warning triangle, too.


BMW Z48/10

Convertibles and safety don’t often fall in the same sentence, unless its one where a concerned relative is trying to convince you not to buy one.

In any case, the Z4 benefits from four airbags (dual front and dual side), as well as the expected electronic stability controls. That optional M Sport differential will have the added bonus of preventing any unexpected slip and slide at the rear.

On the active side the Z4 gets ‘Driving Assistant’ which includes forward collision warning (FCW), lane departure warning (LDW), rear cross traffic alert (RCTA), and rear collision warning. The 30i grade also gets 'active cruise control with stop & go' which allows for full auto emergency braking (AEB) with pedestrian and cyclist detection. Not on the spec sheet, but apparently present in the car I drove was some form of traffic sign recognition (TSR) and lane keep assist (LKAS).

A nice high-res reversing camera displayed on the massive touchscreen is a welcome standard addition.

Considering the meagre safety specification of most convertible cars, the Z4 30i shines with a half-way decent active safety suite. But you can forget ISOFIX child-seat anchor points. There aren't any. 

Ownership

Mercedes-Benz C-Class7/10

The C-Class is covered by Mercedes-Benz’s three-year/unlimited kilometre warranty. We’re keen to see Mercedes-Benz move to longer warranty periods as is becoming the norm with mainstream brands, many of which are offering five year coverage.

Servicing is recommended at 25,000km/12-month intervals for the regular C-Class cars and the C 43. The C 63 S needs servicing every 20,000km or annually.

It’s great to see Mercedes-Benz offers capped price servicing. For example, the C 200 will cost you $396 at its first service, the second is $792 and the third is also $792.


BMW Z46/10

If recent quotes are anything to go by BMW is set to stick by its lacklustre three-year unlimited kilometre warranty, as it says its customers simply aren’t interested in five years (or longer) when it comes to warranty coverage.

It’s a shame, as even Volkswagen has upped its warranty to five years, and Mercedes has considered a 10-year coverage plan in the past.

In terms of servicing, there are two fixed-price plans available – the suspiciously cheap ‘Basic’ plan which comes at a cost of $1373 for five years (or $274.60 per year) and the more realistic-sounding ‘Plus’ which costs $3934 over five years (or $786.80 per year).

Like every other BMW, the Z4’s computer tells you when its service time: how often it needs maintenance will depend on how often – and how hard – you drive it.
