I have a lead on a 1967 Cougar (GT) with a 390 V8 automatic. The car has the C-6 tranny and 9-inch rear end. The body is solid with some very minor rust around the rockers and trunk. The interior is in good shape with some minor wear and some replaced interior pieces (carpet and headliner). The front end has been rebuilt and the car has all new springs. It has a new dual exhaust and rebuilt disc brakes. The car was in a left-side wreck but has been repaired. Unfortunately, the door was replaced and the data plate is missing but the original VIN is still present on the fenders so I'm fairly confident it's an authentic GT. The engine is out of a 68 cougar and was rebuilt but has a few aftermarket pieces (Eldebrock manifold). The car runs strong but the paint is faded and needs to be buffed out and/or repainted. The owner won't part with it for less than $7,500. Is this a fair price?
