By Graham Smith · 07 Aug 2015
For a long time Mercedes struggled to get on terms with the BMW 3-Series, which was slaying them in the compact prestige market, but the C Class launched in 2007 was good enough to finally get the three-pointed star into the game.

Used Mercedes-Benz C63 review: 2008-2009
By Graham Smith · 12 Nov 2010
While most motorists seek reliability and economy from their cars there are those who put performance above all else.For them cars like the Mercedes-Benz C63 AMG deliver the ultimate driving thrill, they're the ones that take performance to previously   undreamt of places.The sad reality for most who lust after a true high performance car, like the C63 with its $126,000 price tag, is that they're well beyond the reach of all but the very, very well heeled.Everyone else can only look on and dream, at least until the price drops to a point they can afford to turn the dream into a reality with a secondhand example.MODEL WATCHThe Mercedes-Benz C63 rewrote the book on performance, lifting the bar even higher than its awesome rivals from BMW and Audi.The pocket rocket race can be traced back to the humble Minis, Cortinas and Escorts of the 1960s, but really started in earnest when   the Germans got in on the act in the 1980s.It was back then that BMW launched the first M3, a hot derivative of the 3-Series. Not to be outdone Mercedes-Benz answered with a hot AMG-  tweaked C-Class, and the race between the German carmakers was well and truly on.  Almost 30 years later and the race is hotter than ever, with each company quick to counter any move its rivals might make.The C63 answered BMW's move to slot a V8 into the M3, and raised the performance bar even higher with its own V8 that boasted 336 kW at   6800 revs and 600 Nm at 5000 revs.It was enough to have it doing 100 km/h just 4.5 seconds from rest, which put it in elite high performance company with cars like the Porsche 911.  Like all AMG models the C63 starts with a modest regular production model, in this case the compact C-Class sedan and wagon.It then gets a much hotter heart, in this case a thumping great hand-built 6.2-litre double overhead camshaft V8 engine.  But while the V8 gave it the grunt the C63 was much more than mere power, it had the chassis to back it up.If there was a criticism of previous C-Class AMG cars it was that they weren't very engaging for those who wanted to be fully involved in the driving. That was countered in the C63 with the seven-speed auto transmission with shift paddles under the steering wheel that gave the driver more control than in previous models, and sharper chassis tuning.It also came with a comprehensive array of electronic devices to monitor and control the car, including electronic stability control, traction control, ABS anti-lock brakes with optimum brake force distribution, emergency brake assist and the like.While these systems help keep the booming 'Benz on the straight and narrow the driver could, if they wished, switch it off and fully enjoy the full thrill of the beast beneath.  Then, if things went wrong the car would engage the electronics in an effort to save the situation before it got too out of hand.Inside, it had leather sports seats, a sports wheel, auto air, cruise, park distance control, six-speaker CD sound, power front seats with memory, power mirrors and windows, sat-nav and woodgrain trim.IN THE SHOPIndependent Mercedes-Benz specialist Peter Lennox services 10-15 C63s   and tells us that it is a robust and reliable performance car and   little goes wrong with them if they are well maintained.The V8 engine has been in production since 2006 and is very reliable.  Lennox says it's good for at least 200,000-300,000 km, and probably a lot more.The seven-speed auto is also quite bulletproof. It has been around since 2005 and like the engine doesn't give any major trouble, although Lennox says he has seen a few problems with lock-up torque converters in cars that have done 200,000-plus km.If driven hard the front-end bushes can wear out in 50,000-60,000 km.   Check for fluid leaks from the oil-filled bushes, a sure sign the   bushes need attention.Tyres don't last long, particularly if driven hard. A driver who takes care of his tyres will be replacing them every 10,000-15,000 km, but one who pushes the performance limit will be replacing them even more frequently.IN A CRASHWith an electronic arsenal of ABS brakes, Brake Assist, EBD   brakeforce distribution, ESP stability control and traction control the C63 has an impressive complement of active safety features.If that isn't enough it also has a full array of airbags, including dual front and side airbags, and head airbags.  ANCAP hasn't specifically tested the C63, but the C-Class it's based upon is rated at five out of a possible five stars.UNDER THE PUMPMake no mistake the C63 is a thirsty beast; Mercedes-Benz claims an average fuel consumption of 14.5-16.0 L/100 km.OWNER'S SAYA super car for less than 150 grand! It was a deal Carsguide reader Lindsay couldn't resist. In his mind he had attained the ultimate in   motoring utopia. As a 60-year-old who has driven competitively and owned some high performance machinery he felt more than capable of   extracting reasonable performance and pleasure out of the C63, but he finds it almost impossible to get the car off the mark quickly without spinning the wheels and invoking the ESP, and defies anyone to achieve the acceleration time Mercedes-Benz claims. He also shredded the rear tyres in just 13,000 km, something he says is   common on the C63. Despite that he says the C63 is great to drive.LOOK FOR High speed thrillsAwesome performanceRefined and sophisticatedGas guzzlerEats rear tyresGreat bang for the buckTHE BOTTOM LINEAwesome performance yet still refined and sophisticated. 90/100

Used Mercedes-Benz C-Class review: 2001-2012
By Ewan Kennedy · 07 Nov 2012
The small-medium Mercedes-Benz C-Class, while costing significantly more than many cars in its class, is becoming increasingly affordable by the standards of the prestige car market.Though it has been built down to a price when compared with upper crust Mercedes models, the price trimming has been done intelligently and you still get a car that’s well built and uses good quality materials.The C-Class is sold as a three-door coupe, a four-door sedan and five-door station wagon body. Coupes from 2008 to 2011 were called the CLC-Class in an attempt to give them a sportier image. That didn’t seem to work and with the new model of 2011 the C-Class coupe name was revised.This is a rear-wheel-drive car so those travelling in the back seats of sedans and wagons will find themselves a little squeezed unless the front seats are moved forward a notch or two. This situation has improved over the years as the C-Class cars have become slightly larger, but it’s still smart to take the family along during your pre-purchase road test to make sure it suits them.Boot space is good and the big bootlid in the sedans makes it easy to load. The wagon is of the stylish school, with a sloping tailgate that robs the load area of some cubic capacity.Naturally the back seats and boots of the coupes are on the cramped side, but that’s par for the course.Few cars come with such a staggering range of engines as the Mercedes C-Class. Four, six and eight-cylinder engines are offered. The latest petrol engines have direct petrol injection and are significantly better than the older units in terms of performance consumption and emissions. Look for the letters CGI in the car’s title, indicting the new-generation engines. The name Kompressor in the car’s title means it has a supercharged engine to provide extra torque. Later units use a turbocharger rather than a supercharger.The hot AMG models use the V8s and have tremendous performance, but this comes at a cost in high fuel consumption.Mercedes-Benz C-Class with turbo-diesel engines have been sold for many years, long before they became common in other European marques. They have either four or six cylinders. The newer diesels (look for CDI on the badge) are a big advance on the older diesel in smoothness and refinement and once the car is cruising at a steady speed we defy you to pick them from petrol powerplants.The great majority of C-Class Mercedes-Benzes will have an automatic transmission, though you will find some four-cylinders cars have a five-speed manual gearbox, they may cause real hassles at resale time.Luxury levels are Classic, Elegance, Avantgarde and Sport. The latter has firmer suspension for better road feel and will make a nice car for the enthusiastic driver.Spare parts, servicing and repairs are all expensive for a car of this size, but certainly not for a machine with the high prestige rating the Benz affords you. Insurance costs are generally reasonable for a car in this class.It pays to buy a used Mercedes-Benz which has been serviced throughout its life by an authorised dealer. Their mechanics are not only trained to high standards, but are in constant touch with the factory. A car with a full service history will almost invariably command a higher price but be sure the service books are genuine.Mercedes-Benz Australia offers a good used-car scheme on cars up to five years of age. The length of the warranty varies according to the workshop’s assessment of the car.WHAT TO LOOK FORBe sure the steering is positive with no unnecessary free play in the straight-ahead position. There were some problems with the early version of the Brake Assist System (BAS). These should have been rectified by a dealer after a recall. Contact the dealer or Mercedes’ head office to see if this work has been done.Do a visual check of the car inside and out for signs of damage or worse-than-average wear. Pay particular attention to the bumper-bar corners for signs of paint scrapes. Also have a good look at the condition of the seats.Always call an expert for the final say no matter how good the Mercedes appears to be after your own inspection. Either use a mechanic formally trained on Mercedes or a senior inspector from your motoring association. Noisy engines, or units that are slow to start may be about to rack up an expensive repair.CAR BUYING TIPIf you’re considering getting an old prestige car rather than a new, but somewhat mundane, car make sure your budget is up to the task of supporting the higher running costs of the upmarket machine.

Used prestige cars review: 2009
By Neil Dowling · 07 Mar 2013
Choosing the right car can open the door to the executive floor, or confirm your corner office and that overdue promotion to the big league. Just as the right suit, tie, shoes or watch send a message to management, so does the right car.Working on the basis that you should always dress for the job you want, not the one you have, there are some impressive buys around in the prestige class. And, better than anything, a smart second-hand purchase is a great way to reward yourself.You still need to think about the obvious stuff -- maintenance and repair costs, insurance, fuel economy and resale value -- but driving a tasty import doesn't have to mean a second mortgage. Buying near-new, with just a couple of years on the clock, can open the doors to some impressive cars.Here are three that tick the boxes for the Carsguide undercover crew:(Search for hundreds more choices)HOT TIPSIf out of warranty use a brand specialist mechanic. If you can find a manual you're sure to save even more. Prestige cars cost to maintain so budget for this.2009 BMW 323iEngine: 2.5-litre 6-cyl petrolTransmission: 6-speed autoThirst: 8.8L/100CARSGUIDE SAYSA BMW badge is enough for many people and it needn't break the bank. The upmarket E90-model 3 Series sedan has balanced and subtly arresting style. The 323i (or the E92 325i if you spend $50K) gets a six-cylinder engine and earns more street cred than the four-cylinder 318i and 320i. It's not cheap to own or run, but the 323i still has lots going for it. It has room for four adults, is an exhilarating drive with solid handling, and even the fuel use isn't too bad. A thorough service history is mandatory and new owners are expected to continue this trend.2009 Lexus IS250 PrestigeEngine: 2.5-litre 6-cyl petrolTransmission: 6-speed automaticThirst: 9.7L/100CARSGUIDE SAYSAn underestimated car that's perfect for first-time executive buyers. This particular example is the desirable 2009 upgrade model and gets extra kit such as the heated and cooled front seats and satnav. The IS is similar in size to a 3 Series but more focused on comfort and equipment than performance or rip-roaring cornering. Lexus builds beautiful cars and owners report very good customer service.2009 Mercedes-Benz C280 AvantgardeEngine: 3.0-litre 6-cyl petrolTransmission: 7-speed automaticThirst: 9.4L/100CARSGUIDE SAYSThis C-Class variant is a cut above the 1.8-litre petrol and 2.1-litre diesel models that sold best in 2008-10. Its 3.0 V6 gives punchy performance, at the cost of a greater thirst, as well as a distinctive exhaust note. There is commendable safety and reasonable equipment, although it's not a match for the Lexus.

Mercedes-Benz C200 2009: Topping up transmission fluid?
Answered by Graham Smith · 03 Apr 2015

If it has a dipstick it can, but you'll find your car doesn't. Automatic transmissions these days are so-called "filled for life", which means they're filled with fluid at the factory and there should be no need to regular checks or top-ups. If you want to change the fluid, which can be a good idea, you need to go to an auto trans specialist.

What's a reliable 4WD?
Answered by Graham Smith · 07 Dec 2018

In terms of reliability and common faults there is little difference between Mazda, Honda and Toyota. They are all good, reputable brands building cars of a good quality with few reliability issues. Choose the one that best suits your family needs.

I HAVEN'T and I couldn't believe it, but I contacted Mercedes-Benz to check anyway. It confirmed my belief that your friend's information was incorrect, but to be sure Benz told us it would contact you to get more information and hopefully set your friend's mind at rest.
