I'll admit it.... Brand X that I really like, and it's a GM.

My first A bodies were a 67, then a 65 GTO/lemans respectively. The 7 had a 400 and the 5 I stuffed in a 455. both 4 speeds for awhile then the 5 got a Richmond race 5 speed no syncro. There was some fun there. I do like the buick GS as its somewhat oddball and a bit sleeper with some of those powerplants they came with.
