A friend of mine's dad that I've know since I was about 9 years old has a 4 speed GSX that he bought brand new in 1970. This guy is a well reknown restorer of antique's and those are his first love but his muscle cars are unbelievable. The GSX has less than 10,000 miles. He also owns a 70 hemi Superbird with approx 600 miles that he must have bought sometime around 72-73(I remember him bringing it to a little league game we were in) and a 70 442-W30 with low miles.
Anyway, he was recently offered 200k for the GSX according to his son, but he didn't take it. Obviously, this guys no flipper
