Always an eclectic mix of cars, designer Peter Brock was there as well as Tom Peters, part of the design team for the new Corvette. Pete was very instrumental in the early days of the Corvette racing team and did a bit of work behind the scenes to make the designs possible. He current has his own company in Las Vegas. GM let out the Mako Shark Corvette for the event as well. (Many thanks !)

Beyond Jay Leno, who helped with QA sessions, if you check a couple of the later shots in the set, Steve Perry, former front man for Journey was also in attendance.
