A friend of mine is looking to buy a replacement for his tatty but reliable C180 . Budget is limited to £6.5k , and he is not into classics. Doesnt like A- class , rather likes c--- cdi . What can he expect in this price range , and equally important , which models/years are best avoided ? Needs best combination of reliability/economy . Any sensible ideas please ? Prefers 4 door , no estates. Cash buyer , no p/ex .
