Which used Mercedes S-Class saloon should I buy?
Whichever luxury car you're after, the brief is the same: buy the ones with the smallest engines. Every model has decent performance and even the smallest version delivers nine-tenths of what you'd get if you bought the flagship version - but at a knockdown price.
The S320 CDI diesel is our first choice, followed by the smallest petrol, the S280. These were the best sellers, so there should be lots around.
Other models include an S350, S500, S600 and the performance flagship, the thundering S65 AMG, which offers no less than 612bhp. Of these, only the S350 is anything like a sensible choice.
Each model has a single trim level, with loads of equipment that includes leather seats, climate control and the Comand system that runs the sat-nav, stereo, phone and other gadgets. However, the list of extras for the car is so long that we've not seen two identically equipped.
