2002 M3
 

One of my friends is looking into buying a 2002 m3 with 85,000 miles on it, i'm trying to help him get a good price on it, are there any known issues out there that he should be looking for? What about service intervals and cost. I believe I read an inspection 1/2 should be done at 15k and 30k respectively. Thanks for the help.

I'm going to do some searching on my own but any insight you guys can give is much appreciated.
