When i bought my 65 the dealer had a 66 formula S also and I test drove both cars. Both cars had the 273 Commando but the 65 was'nt a formula S. Only thing about the 66( and it was Black too!). it was an auto. The 65 was a stick(just a 3 on the tree)...but when I floored it in 1st gear I was sold! The 66 was clearly a nicer car but i had to have a stick...i'm an old geezer and autos were'nt too cool back then.(1969) I always wanted to put a 4 speed in it but college and other stuff($$$) got in the way. Now I have 67 Cuda drag car work in progress, but still want a 65 that i can drive and criuse with like you do with yours. ahhh, maybe soneday...
