20 Muscle Cars That Made History

Yeah I should have just said 2dr.

GM took the mid-sized '64 LeMans 2dr, stuffed a big motor and heavy duty components in it, a separate GTO only option package of trim/interior, gave it it's own separate model designation and gets credit for having a novel idea.

IMO, Plymouth beat them to the punch by 8 years with the Fury. Just don't tell the GM guys, counseling and anti-depression drugs are probably expensive.
