I just picked up a 1988 735iL 2 weeks ago good condition until today the rumbling started and I feel helpless 107K Miles per the title since the Intrument panel LED is broken I dont the real mileage. But paid 2K$ that is a steal as long as the body is mint even if you drop another 2K$ to get the car to good condition. I'm sure that the resale value still remains hign on the BMW.
Good luck happy hunting. I picked up my car in Brooklyn Paywayless auto. The guy said he has a 1990 740IL mint condition. Found that guy from Cars.com its a good site just invest on Carfax.com 24$ and check the VIN of the car you desire for your own protection.
