What should I look for in a used Mercedes S-Class saloon?
The What Car? Reliability Index paints a poor picture of the S-Class and puts average repair costs at a whacking £600. However, that figure also encompasses the previous model, and we would expect this model to be much better.
There's no doubt it's a tough car, and the engines and transmissions last indefinitely if cared for, although the electrics can go haywire.
