OMG a Z06?
Have you ever driven a vette... Personally I think they suck. Cheap ass piece of shit, too much power, no tracktions, looks like crap (IMO), LOUD a$$ fuel pump, no elegance factor, everyone has one.
As for the Z06 vs an NSX. Prefferable the NSX would be the Type-R to make it fair. In a straigt the Z06 would win, but for everything else I'd expect the NSX to win, especially in style, comfort, handling.
Although looking at Z06 stats, skidpad numbers, .97-.99g.
I can't find NSX-R Specs for skidpad though.
Video = YEAH! (not a great vid though)
