what do you think of a 1983 BMW 320i with 150,000+ plus miles? i'm a student looking for a car and have been offered one. what is the price range of these cars (pretty good condition, some rust)? how well do these BMWs hold up? how hard is it to find replacement parts for them? if you can't tell, i'm not much of a car person and would welcome any advice you may have. please email replies as well as post to board. thanks
