EZ,
I think they use SRT stuff... Grand Cherokees, Chargers and 300's. Not sure if they use Vipers and Challengers. If you are in the US, the "experience " is free if you own an SRT vehicle. Being Canadian, we have to pay $500, even though I own two SRT vehicles... hmmmn, discrimination.
I might check out the drag stuff some time. I've been to the races at Indy and Columbus and had a ball (watching, not racing). Being there live is truly a treat (assault?) on the senses... sound and smell especially. Even the bitch I was married to at the time enjoyed it and that's saying a lot!
