i'm looking at a 89 e30 m3. it is red/black int., 5 spd., and has 72+K miles. they are asking $12K. i know i should probably get a e36 but this one looks just like the first BMW i saw as a kid and sparked my interest. what can you guys tell me about the e30 m3. problems? things to look out for? i know it is a 4cyl. but is it better than like a e36 328? thanks in advance!
