Mercedes-Benz C-Class Problems

Obviously you're in the market for a performance drive, and the biggest difference between your preferences is seats. Specifically, just two in the Porsche. So, despite the fact the Cayman has a pretty handy boot in the nose, it's never going to be as practical as a C-Class sedan. The 6.2-litre V8 in the (W204) C63 is a naturally aspirated dream. The sound and fury of 372kW/620Nm (in the Edition 507) driving the rear wheels is a rare pleasure, and on the right road, its balance and mid-range punch are sublime. The current (W205-based) C63 S's 4.0-litre turbo V8 just pips it on outputs (375kW/700Nm), but the biggest difference with that unit's forced induction is that all that torque is available from just 1750rpm. The new chassis is brilliant, and is even quicker point-to-point than the Edition 507. Then there's the Cayman. Although we've somehow missed seat time in the GT4, experience with previous ‘special' models, including the (881) Cayman R and GTS point to this being the purest (or purist's?) choice. The 3.4-litre atmo R produces 243kW/370Nm, the GTS 250kW/380Nm, and the 3.8-litre GT4 is at 283kW/420Nm. The Cayman's mid-engine layout, and ideal weight distribution makes it one of the most precise and agile sports cars on the planet. So if you can live with just the two seats (that aren't exactly easy to get in and out of), it's our pick in terms of outright driving enjoyment.

With a limited budget like yours I would suggest to go for a car with a good reliability record. While the Mercedes-Benz is a good car you are likely to be facing an expensive repair if anything should go wrong. Consider a Mitsubishi 380 or a Toyota Camry of around 2000-2003.

The oil fill with the filter is 5.5 litres, or 5.0 litres without.

Mercedes recommends you use 95-octane Premium fuel, but you could also use 98-octane. Do not use 91-octane regular unleaded.

Normally I would have expected the car to run roughly when the chain stretched. They stretch progressively, not overnight, so there should have been some warning that all was not well. But it is low kilometres for a chain to stretch, which might mean you have a case for a goodwill claim against Mercedes, although I wouldn’t fancy your chances of success.

I suggest that you take it to an independent Mercedes mechanic and get a quote from them. It is almost certain to be lower. You could also investigate importing the parts from an overseas source, such as a Mercedes dealer in the USA, and have them fitted here.

There is nothing sinister or underhand here. Car companies rotate their plates on to their newest models to make life a little easier for their fleet administrators.

Electrical problems can quickly become costly but you will notice a big step down in comfort and class if you downgrade to a Hyundai. It's a sensible move on the budget front but make sure you understand the implications — take a long test drive in the Accent before you commit.
