This S-Class looks sleekly poised and is less of a heavyweight than the previous model, though it has retained its imposing identity and presence. Thanks to the Active Body Control system the handling is sharpened up so much that the old car feels stodgy by comparison.

Running costs

You can achieve relatively decent economy from the diesel engine, but beware of being hit by big tax demands if you choose it as a company car. Servicing isn't cheap either and if something does go wrong, expect to pay a premium for parts.
