I'm looking to purchase a 93 325is, I don't know much about the color besides the fact that it's black and clearcoated... metallic or not that I don't know. The cars in Santa Cruz and I'm in Los Angeles. Do you think its worth the trip? I have a couple of pics showing oxidation and cracks on the roof, can you guys tell me whether I'll be able to buff the cracks out with just a PC? And what approach would you guys recommend? Thanks in advance.
