You know, I'm usually the first to scoff at the oddball "fish" story, but as the internet has grown, I've learned to keep an open mind. I would bet there were probably 20-30 1970 RAIV GTO's made with no options. As for standard 70 GTO's, probably 1 or 2 with no options. The RAIV was billed as a semi-race engine, and I'm sure more than a few people ordered one to race. Until the advent of the internet, we never would have heard about some of these cars unless they appeared in a magazine, at a national show, or you knew someone that had one.
I saw a very rare 70 W-30 4-speed car a few years ago that was a post coupe, W-27 rear, with absolutely no options. It even had a heater delete. Someone definately ordered this car to drag race.
Then there's the story of those 6 factory lightweight 65 GTO's...
