If you've got 1.2 seconds to spare on your way to the big dance, I can save you $515,500 (before my modest commission for saving you such big bucks)
Behold American Engineering Marvel: 2006 Corvette C6 Convertible, Zero-60 in 4.2 seconds with the reliability of your Chevy pickup truck and a price tag of $44,000 for the Coupe. (Convertible shown, Babe not included in price, but might be attracted by your new ride)
I did not realize that today's 'Vette's were priced so reasonably for that kind of performance. They still do have that stigma attached to them, though, which Chevy never tried to deal with.
