I'm in the market for a bimmer. I have found one that I would like to buy it's a 1992 535i. It's a fair price and it looks like it's in great shape. I was wondering what kinds of questions should I be asking the seller? Facts I know about the car: 5 speed manual transmission, recently painted front end, 147k miles, performance chip, M5 replica rims, pedals and parking brake are M-style, and brand new cd/audio system. Thanks for any help.
