Ferrari f430 or Corvette ZR1

I'm not familiar with the ZR1's bumper construction - is it fiberglass or will it sag after a few years like every other commodity car? Ferrari bumpers are eternally as perky as the first date

Alas, the Vette will be just another Chevy in four years whereas the Ferrari will still be something noteworthy. But this is my opinion... I value cars that have "staying power". All the ZR1 has going for it is some technical data, and once that becomes obsolete (say, Nissan beats it next year) then what do you have??? Just another Vette that "was the fastest" but is now worth 1/2 what you paid and the bumpers are sagging because they are polymer instead of glass.
