Just had a full service incl valve adjustment no underbody rust (the car had Ziebart rust prevention treatment there are just a few bubbles near the fuel filler see pics)Paint looks original but some panels have been resprayed a few stonechips have been touched up.Air-conditioning works and blows cold ...All gauges work but have a quirk and there is a ground short somewhere as the charging light lights up but the alternator produces 14V I'm including a new alternator and a new speedo cable as the installed one clicks between 30MPH and about 50MPH The paperwork indicates the the motor has been rebuilt at 80374 miles in 1984I bought the car out of a large collection and believe that it only has 104000 miles but can not verify thisThe electric roof works but should get a new rear seal....A few little things for the new owner to fix but nothing major I drove the car in the Carolina mountains and it drives amazing....just beautiful
