I have a 1994 C180, a four cyl engined car which is pretty good in fuel consumption, braking, quiet drive and quite confortable suspension. However, power is definitely lacking and many times I have to resort to the kickdown to help me get along faster. The car goes very well at speeds above 80kmh, but at lower speeds you feel the road bumps a lot like over rail and tram tracks and small holes. Could be the shocks need replacing or they are the sports ones, I don't know. It has the rear headrests which collapse with the dash button, manually pulling it up. Problems since buying 2 years ago were, replaced whole exhaust system, front bushes, water pump, tensioner, belt, fuel pump and filter and battery, 2 vacc actuators under the dash, brake pads, plugs, filters and oil. Mileage is now 196500km.
