Guess I should register here. I currently have one on the 50 Festival cars #44 and one of the 153 M6 manual dealer cars.
There is a Camaro Pace Car site at
http://www.camaropacecars.com
They have a private registry of all years of camaro pace car owners.
There were actually "51" 2011 Camaro Vert Festival cars and it was purchased by Jon Bon Jovi who also has a matching 69 pace car.
Plus there were a couple of coupes used as festival cars too...
