For $15 we were able to watch 2 days of vintage car racing, see a huge car show, and drive several different cars. I drove 3, the least valuable of which was a 2011 Corvette Grand Sport ~$55,000, the next would be a 2011 E63 AMG ~$88,000, and last was a SL63 AMG at a cool $140,000.
The Corvettes were in an open area, thus you had to have a GM employee passenger to keep tabs on you :(
The Mercedes people had basically an auto-cross course set up. They put you in the car and told you the objective was to keep the cars moving...YEAH!!! Here are MORE PICTURES.
