Here's an account my friend posted of his run in with the C7, Z06 Stingray prototype and talk with the GM engineers: http://www.corvette7.com/forums/showthread.php?t=379
Long story short: he spotted a base C7 with silver wheels and no spoiler together with a camouflaged Z06 being tested by GM engineers on their way to the Yuma proving grounds. They wouldn't let him take photos of the Z06 though
