Due to my experience in the past with the BMW dealer I asked a collegue that drives a newer 528 and he recommended these guys.
Prompt service, VERY professional, and the guy behind the counter had a wicked sense of humor. Asked a few random questions afterward and they answered...
The only place I would ever take my car period. Great service, honest, family run business that treats its customers like family
Heard great things from many other J&J Motorsport customers, looking forward to BMW service when needed.
