I plan on purchasing a 2002 M5 and keeping it for 8 to 10 years. It would be used as a daily commuter, not a car to be driven only on weekends or on fair weather days. How reliable is everyone finding their M5s to be? I'm not an idealist and realize there will be some problems because the M5 is a high performance car. But, I don't want to have to be taking it to the dealer every month either. I apologize for the long post. Blk on blk, M audio, PDC, and folding rear seats.
