Mercedes-Benz C250 Problems

New-age diesels in every size and price class promise more kilometres from every litre and more kilometres between refills, thanks to massive advances in efficiency and refinement.The days when diesels were black-smoke rattlers, and only favoured by farmers with a diesel tank to top-up their Benz or Peugeot, are long gone. The diesel-engined Ford Territory easily outsold the petrol-powered model during its first month in showrooms, reflecting the backlog of buyers who now put diesel first.But is diesel the right choice for everyone?Petrol power is also more efficient than ever in 2011, LPG is making a solid surge, especially with a new gas-powered Falcon on the road and a Commodore coming soon, and it still costs more to choose a diesel.At the most basic level, new-car buyers need to work out how quickly the extra cost of a diesel car will be recovered. If it takes three years and you plan to keep the car for five, that's all good. But if it takes seven years to make up the difference and you only plan to keep the vehicle for five, then ... So it's a horses-for-courses situation. The more you drive the more a diesel makes sense.Diesels generally have the advantage of lower fuel consumption, and many modern diesels can also get 1000 kilometres from a single tank, as well as a tougher engine to cope with the higher compression and better values at resale.Diesel is already the first-choice pick with some luxury brands, as BMW's diesel-powered fleet has outsold the petrol models through the first half of 2011 and Mercedes is also reporting record diesel sales on its C and E-Class cars.Most European-built cars have always had diesel variants and the 4WD and SUV classes have also been long-term diesel strongholds, but the move to maximise fuel efficiency means they're also appearing in baby and small cars in Australia.It's in these price-sensitive segments where choosing a hi-tech oil-burner can represent up to 15 per cent of the cost of the car. Buying a diesel Holden Cruze adds up to $4000 to the price and if you pick a Ford Focus with diesel the extra cost is around $4300.The good news is that diesel cars will maintain their price advantage at resale time, says Glass's Guide managing director Santo Amoddio."The only area where the diesels aren't strong is the manual four (cylinders)," he says. "In Europe it's the sensible way to drive but Australians have yet to embrace the idea of manual-powered small diesels, so the used values reflect that."Amoddio says diesels are a quick way to cut fuel use and CO2 emissions."There's a lot of talk about electric cars and hybrids but I think diesel is the way to go for private buyers at the moment in terms of costs of running and resale," he says. "That's especially the case in the medium in large SUVs. For example, we expect the turbodiesel Ford Territory to outsell the petrol model. It's probably two years too late to market but it's a good engine and will suit that application."The diesel engine in the Territory is up to a $5000 option but in this class people often believe they need the extra towing capacity of the diesel, yet then don't order the heavy-duty towing pack, which pulls it back to the 1600kg the six-cylinder petrol engine can haul.At Ford's claimed fuel use rates of 8.2 litres for the diesel against 10.6 litres for the petrol it will take about six years travelling 15,000 kilometres a year (assuming the same pump price for both petrol and diesel) to recover that five grand.The relative difference between diesel and petrol models isn't usually as big on SUVs as it is with the smaller cars.Choose diesel on a Toyota Prado and it's a $1000 premium, while Subaru's Outback is $2000 more with a diesel donk - but only comes as a manual - and the Mitsubishi Pajero is around $3000 dearer with an oil burner.Step up to the larger off-roaders and Nissan's turbodiesel Patrol is $3000 cheaper than the comparably-equipped petrol model, Range Rover offers $500 off its diesel Evoques and diesel is the entry option for Audi and BMW's SUV ranges.Diesel is even the preferred option for the Toyota LandCruiser despite its $10,000 dearer purchase price.The traditional argument that servicing costs are higher is also starting to lose momentum. Ford has capped servicing costs for the new Territory and the diesel is only $20 dearer at $290 for each visit to the dealer.It's a similar story with the Polo - over the first five services and/or five years the diesel is about $100 cheaper to maintain at $1910."If you know what you plan to do with the car it isn't hard to work out whether you should buy diesel or petrol," Amoddio said. "About five years ago diesels accounted for 1 per cent of passenger vehicles in Australia - now it's nudging 10 (per cent). It's the improvements in refinement that have driven that and we see that trend continuing."VW Polo ComfortlinePetrol (diesel)Price: $19,850, ($22,350)Engine: 1.2-litre turbo petrol (1.6-litre turbodiesel)Outputs: 77kW/175Nm (66kW/230Nm)Transmission: Six-speed manual (five speed manual), front-wheel driveFuel use: 5.5 litres/100km, 128g/km CO2 (4.7 litres/100km, 124g/km CO2)Weight: 1048kg (1115kg)Price after three years: $10,900 ($12,500)Percentage of new cost: 55 per cent (56 per cent)Annual fuel cost* $1152.30 ($979.21)Diesel saving of $173.09 a year means it would take 14.4 years to recover the $2500 difference in purchase price.Holden Cruze CDPetrol (diesel)Price: $22,240 ($24,990)Engine: 1.4-litre turbo petrol (2.0-litre turbodiesel)Outputs: 103kW/200Nm (110kW/320Nm)Transmission: six-speed manual (both), front-wheel driveFuel use: 6.4 litres/100km, 146g/km CO2 (5.6 litres/100km, 147g/km CO2)Weight: 1329 (1489)Price after three years: $11,100 ($15,100)Percentage of new cost: 50 per cent (51 per cent)Annual fuel cost: $1340.86 ($1166.72)Diesel saving of $174.15 a year means it would take 15.8 years to recover the $2750 difference in purchase price.Mercedes-Benz C-Class 250 AvantgardePetrol (diesel)Price: $67,900 (both)Engine: 1.8-litre turbo four-cylinder (2.2-litre twin-turbodiesel)Outputs:150kW/310Nm (150kW/500Nm)Transmission: seven-speed automatic, rear-wheel drive (both)Fuel use: 7.2 litres/100km, 167g/km CO2 (5.1 litres/100km, 134g/km CO2)Weight: 1480kg (1587kg)Price after three years: $36,700 (both)Percentage of new cost: 54 per cent (both)Annual fuel cost: $1508.42 ($1062.54)The same price for both cars means a diesel Merc owner will pocket more than $445 a year in lower fuel bills.Ford Territory 2WD TXPetrol (diesel)Price: $39,990 ($43,240)Engine:4.0-litre six-cylinder (2.7-litre V6 turbodiesel)Outputs:195kW/391Nm (140kW/440Nm)Transmission: Six-speed automatic, rear-wheel drive (both)Fuel use: 10.6 litres/100km, 240g/km CO2 (8.2 litres/100km, 217g/km CO2)Weight:Price after three years: $22,000 ($25,100)Percentage of new cost: 55 per cent (58 per cent)Annual fuel cost: $2220.81 ($1708.40)Diesel saving of $512.41 a year means it would take 6.3 years to recover the $3250 difference in purchase price.Toyota LandCruiser 200 VXPetrol (diesel)Price: $88,414 ($98,664)Engine: 4.7-litre V8 (4.5-litre V8 diesel)Outputs: 202kW/410Nm (195kW/650Nm)Transmission: Five-speed automatic (six-speed automatic), four-wheel driveFuel use: 14.5 litres/100km, 341g/km CO2 (10.3 litres/100km, 273g/km CO2)Weight: 2610kg (2675kg)Price after three years: $53,900 ($60,200)Percentage of new cost: 61 per cent (both)Annual fuel cost: $3037.89 ($2145.92)Diesel saving of $891.96 means it would take 11.5 years to recover the $10,250 difference in purchase price.*Fuel costs calculated based on national petrol average last Friday of $143.5 a litre for petrol and $142.7 a litre for diesel.

Mercedes-Benz has just launched an all-new C-Class model, so there's a good chance many owners of older models will be trading up. Meaning there could be a glut of used C-Class in Australia, giving you the chance to select between the many on offer, as well as the opportunity to select from the best of them. 

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.
