Manthri - further to the pm I sent you, I saw a nice coupe in that same price range at Katie's Cars N Coffee last weekend. (Katie's, in Great Falls, VA, is the largest Cars N Coffee east of the Mississippi). The owner acquired the car in question from a customer of the independent BMW shop he ran before he retired. The owner knows BMWs well, and has some outstanding vintage cars.
The car had been a restoration candidate, and is reported to be rust free. (Obviously rust free is a term that requires definition any time you are looking at a coupe). It was purchased because the restoration did not go forward. The car had been a big bumper car, and the diving board bumpers have been removed. The front is completely bumperless; the rear has a close to the body csl replica fiberglass bumper. The car is said to be well sorted mechanically, and given what I know of the owner I would be stunned if this were not the case.
I have no financial interest in this deal. I just happened to be walking around with an acquaintance who is also into BMWs and expressed interest in the car, so we spent a little time looking at it. I know how to evaluate an e9, but determined not to inject myself into the process with these two.
This car is presentable, although not as pretty as the one you are considering. PM me if you want more info and I can put you in touch with the seller.
