Gev IV ACR for still being the King of the 'Ring
Ferrari Enzo with so much F1 technology transfers, especially that nose....
Ford GT for having such timeless lines and most beautiful (to my eyes at least) and can top 200 MPH at the mile (with standing start) w/ minor mods.
Porsche 959 for the 4WD tech and being the grand daddy of all current era Turbos.
But the all time great award has to go to the McLaren F1 - fast, light, raw, and the Ménage à trois seating arrangement (I used to fantasize about owning the car and having two..... never mind)
No room for the Pagani Zonda which I'd place sixth, sorry...
