I agree. Costs of restorations are keeping up with inflation. $70k doesn't seem out of line. Especially when considering less than 400 total 4spds built and its all numbers matching. I believe the similarly equipped, Black/Black, unrestored 4spd , previously 1 owner car, 71 GTX brought 50k a several years back.
