I'm looking into buying a new car. Well, not a new car, a 1983 733i. I haven't had the pleasure to fully look the car over, but I'm curious if there are any recurring/well known problems to look for in the car. It's a 5speed manual, 200k miles. Body looks nice, but again, I haven't had the chance to go and really examine the car. I've been told the car runs strong, but anyone know about how long I could expect these motors to run before a swap/rebuild? Also, how are these things known for upgradeability? Perhaps dropping a larger motor? I want a nice car, nothing street racer, just a nice car that can move when it wants to =) The person is also asking 1500, but I feel this is extremely steep for the high mileage. Any tips/hints/known problems/anything you know about the car would be greatly appreciated. Thanks alot in advance.
