Just had my 1994 C180 Euro front end levelled out by replacing the rubber spring caps(top and bottom) on the driver's side so that both front sides are now level. The driver's side was 21mm lower than the pass side and it was looking a bit topsy turvy. This is the cheaper way to solve the problem. You can also change both front springs and their top and bottom rubber caps. Your techie would probably also talk you into changing all 4 springs and shock absorbers and bushes and brake rotors and pads. They never fail to find something else to do on your car!!!!
