The two most unique ones besides the SVX were a 1973 AMC Hornet Hatchback (The Green Hornet), with a 360 CI V8, 727 Torqueflite auto tranny, and a modifed Dodge Charger rearend. What a sleeper. Too many tickets, too early in my driving career. Had to sell it. Best 1/4 mile time was a 12.19, can't remember the speed. Not much over 100, though.
The other one was a 1977 Renault Gordini. Very unique, very cool. Not fast or anything, but pretty rare. The whole top opened up as a sunroof. That was another car that nobody could figure out what it was.
