I have the chance to pick up a very clean original 1981 GP LJ with 72K miles. It has the original Pontiac 4.3 liter V8, Metric 200 trans that shifts perfect, rallye wheels with all 4 red centers in place, recent rubber, tuneup, hoses etc, burgandy bucket seat interior that is fade free, working A/C and the body is near mint along with the frame and under carriage. The only problem area is the driver's door which has some surface rust. Does this car sound like it's worth $3500?
