I think the Idea started way back when Car and Driver Magazine road tested the first 240z .That day they had a mgb gt a opel gt and a vw karman ghia .The only words the test drivers kept coming up with was the 240z was Ferrari Like in every way .remember when the 240z came out there was nothing in its price that compared to it .The corvette was a big lump or Iron basicaly a chevy lemans with a shorter wheel base and a fiberglassbody on top very crude for a performance sports car and then there were Ferraris aand really nothing in between that was sleek well balanced and scaled to a personal drivers car .The test concluded with the test drivers wishing for stiffer shocks as the only improvement they thought the car needed to be perfect.
