People always tell me - "Man, parts for that car must be so expensive." I just tell them that the parts for that car are no more expensive than any other car of that age, and in many cases are actually cheaper. I can't speak for newer BMWs, but my experience has been that the commonly replaced parts on the E30s are not really expensive at all. The crappy made-in-China reproduction parts for my Camaro are much more expensive and are mass-produced Chinese quality.
