I currently drive a car that is less than desirable as my personal daily, and I would like to change things up a bit. I have some money saved up and I have been contacted by an acquaintance about their '83 533i that they want to sell. Its really clean but has at least 200,000 miles on it. No rust as of what I know, and starts and runs well. The guy has not given me any margin of price, and only wants me to make an offer as he personally does not know the exact worth. I was wondering how much you would pay for a car in this condition. And the difficultly for maintenance and work you have experienced. Finally, would it be better to wait for an e30 of comparable condition over an e28?
