In 1972, one of my coworkers was joining the Marine Corps and sold his GTO for $1200. It was a black 1967, 389 with twin 4-barrels and a 4-speed. I was 17 and had the money (my college fund), and I will always regret not buying that car, even though my parents would have killed me the minute I drove up in it.
I have a friend who has a 67 GTO like mine. His is red with black interior, mine is black with red interior. Both of us are second owners. I bought mine from the family of the original owner who was going to be a long- term resident of the state of New Mexico in Santa Fe. He got his by trading his 72 Pinto station wagon straight across for it.
