Hmm...do any of ya'll play Xbox LIVE? There is a game called Forza Motorsports 2, and it has over 300 different cars to choose from...including a ZO6. And every car you all have mentioned here. It's really fun...at least I don't have to pay to play it...
EDIT:
Here is the car that I want:
Lingenfelter 'Vette...in other words, awesome.
Google it.
