Mercedes C-Class

* Electrics: some owners report failure of the single steering column stalk that controls the lights and wipers. If it goes, the bill will set you back ΂£200 if the car is out of warranty.

* Engine: six-cylinders and diesels are in-credibly tough, while four-pots usually last for 150,000 miles. Failed stretch bolts in the cylinder head can be costly to repair.

* Gearbox: automatics are usually trouble-free, but abused manuals can feel loose or show syncromesh wear. Check the box feels positive and there's no clutch drag.

* Bodywork: rot simply isn't an issue, as the car comes with a 20-year corrosion guarantee. But be wary of minor body damage, as panels are expensive and some finishes are tricky to match.

* Catalytic conv.: cats on four-pots are known to go pop with less than 80,000 miles on the clock. If the rear silencer is rusting, then the catalyst's welds are starting to go.
Driving impressions
Early examples of the saloon, made in South Africa rather than Germany, were criticised for not having the same levels of build quality as previous offerings. But this was soon sorted out.
The C-Class is now an excellent car, exceptionally well engineered and incredibly refined, and offers tremendous prestige and luxury.
Glass's View
The C-Class remains an aspirational car and its upmarket image, together with legendary build quality and reliability, will ensure that it stays a very sought after model for some time to come. Second-hand values are steady and likely to remain that way for the foreseeable future. The Sports Coupί¿½ isn't as popular as the saloon, while both the Estate and diesel models have massive appeal - especially if they have bright metallic paint finishes and automatic transmission.

Life With A C-Class
My C-Class estate is incredibly comfortable, reliable and a great cruiser, but the supercharged engine is too thirsty. I would definitely buy another Merc, but will probably have an E-Class diesel. John Bayliss, Hove, West Sussex
The C-Class was the only premium car I could have as a company motor, but I wish I had gone for a better-equipped Alfa 156 or Honda Accord. Narjat Singh, Leicester
