I still like the looks of the Avanti.
I'll take one with the round headlight lids and a supercharger, please!
I was born in 1955 and all the cars I consider milestones of car lust (most of them already mentioned here) were around before I really discovered cars in my early teens...just in time for the 1970 Camaro/Firebird, and the Barracuda/Challenger. These were real-life versions of what my classmates and I were scribbling in our school notebooks!
Then there were the Italian supercars of the time, like the Lamborghini Muira (http://www.totalheadturne..com/details.php?Id=481)
and the DeTomaso Mangusta (http://www.lotusesprittur..._Tomaso_Mangusta.htm).
Wouldn't own one even if I could, but Holy Shamoley, just LOOK at them!
