Hi everyone, I'm new around here.
I'm looking into buying a black 1982 528 and was wondering if there is anything I should be warned of before I go any further. The car is an automatic and the owner as informed me that the air-conditioning is not working. I have done a visual inspection and have gathered that the car has been well maintained. The exterior/interior is very clean and I can see no sign of rust but I did notice much oil built-up on the underbody of the car. Is air-conditioning malfunction common in the 528? Your insight and experience would be much appreciated.
thanking you guys in advance
