I'm looking at an '88 325 iC that's for sale near me. It looks to be in good condition. I took it for a drive and she was solid and smooth. I'd like to get an idea of the top ten things to check for with this model. I've owned 2002's and know of their problem areas and was wondering if there's some things that I should be focusing on with E30's. Any advice is much appreciated. Thanks, Gary
