I just called European Motor Sport to do a front and possibly rear seal job on my 1984 300SD. The engine is out of the car and I wanted to take it to them. I figured it would be easier that way rather than putting the engine in the car and then dealing with it. They absolutely did not want to help me at all. I even asked if I put the engine in the car and brought it to them if that would matter. The guy said, "We don't want to do anything with this, I don't know how much clearer I can be than that". So needless to say, they are not to high up on the list as far as helping people out. They did refer me to Star Motors though, the guy at Star was very helpful.
