Welcome to UCP, there is an on-going thread on this subject, but as you wisely put this one in the classic-car section, it is unlikely that we get to see the Enzos and the Veyrons here.

Mine would be
Alpine A110 (possibly a 1600 SC)
Citroen DS
Ferrari 288 GTO
Ferrari 330 GTC
Lamborghini Miura
Chevron B16 (Street legal Continuation model)
BMW 3200CS
Peugeot 406 Coupe HDi 2.2 (Daily driver )
Alfa Romeo 8C2300 Zagato
Lotus Elan S2
