HI I spent several enjoyable hours with the owner. Looked for rust and went through the check list, car did amazingly well in almost all areas. Frame is straight, body is very clean only rust found was a limited section under the radiator. This car is a good restoration candidate as it needs cosmetics rather than engine and ZF Keep in mind that I am not an expert on this so my inspection talent is limited. I had a choice of buying this one or another and the other was closer to what I was looking for.
If I had bought it I would
Get rid of the spoiler fix the paint
Rework the interior, seats, carpet, sound system headliner, refurb the door panels etc, dashboard was in good shape and would need cosmetic restoration.
Find and install the rear bumper
Needs a new windshield wiper motor, needs a new A/C system. Install the valves in the heater system. That was what I could find which in my opinion is reasonable given the age and vehicle cost. Or you could just drive it the way it is and go really fast and be happy.
