Tough one as there's sooo many but ZL2's aside, here's my condensed list...
'70/'73 Formula...'74 & up sucks in comparison! .
'67 SS427 Impala...style kind've stolen from the '63 S.O. Vettes? .
'70 442/W30...don't like the 71/72 w/ grille indent as much! .
'65/'66 Vette Mk1V's...'67's became too common? .
...if Dream cars count, it's the '53 Wildcat hands down! . It's sure a design-style that became common enough also pretty subtle for such a boat...especially for the early fifties! .
Weren't those scoops on Bob's choice '63 Poncho really a Ford sourced item? .
Where's the rear spoiler thread? .
