You can pick up used vettes for pennies on the dollar now. The Z06 is a hell of a bargain as many owners have moved to the ZR1. That's how I got mine.
The Vette team took the 2012 Z06 back to the Ring. Beat the 05 time by over 20 seconds. Came within 3 seconds of the ZR1 time. This one was equipped with the Z07 upgrade, carbon upgrade, PTM and new PS tires. Basically identical to the ZR1 but different drive train (136 less HP, different tranny gearing) and about 170 pounds lighter. Better weight distribution than the ZR1 too.
