Lamborghini 3500 GTZ

The Lamborghini 3500 GTZ was a car designed by Ercole Spada under Zagato in 1965 and built apart from Automobili Lamborghini S.p.A. Lamborghini's management hated it, however, because it looked too much like their upcoming Miura and it very closely resembled Ferrari's 250GTO, though lacking the awesome looks and charisma of that berlinetta.

It is notable in that this car actually represented the only relation between Lamborghini and Zagato (besides the later stillborn "Canto"), the latter was never contracted by Ferruccio, who liked Bertone's designs better, as almost all the Lamborghini designs to follow the 350/400 GT were executed by Nucio Bertone and his design team.
