Allow me to recommend Europa Imports located at 1007 Tower Road in Winnetka, Illinois, phone 847-446-9500. I've been going to them since 1985 for all manner of Mercedes Benz repair, first on my old 1978 280SE (long departed), and now with my 1994 E320 Stationwagon. John Gabler, their Mercedes mechanic, used to work for Mercedes Benz at ******** back in the day, and he is simply the best mechanic around. His brother Michael Gabler runs their auto body facility, where they perform some of the best body work and painting I have seen. Yes, it is out of the way, but certainly worth the trip, and tell them I sent you!
