During the part when Mitch parks his Hummer, and Trey gets air in the garage, look at his license plate exactly at 45:07 (Track 14 on DVD). It says 2TAB345 clearly (you might have to pause it). Later when Trey parks it, it says ICETREY. Also, when "Trey" is speeding and getting air in the garage, if you look closely, you can see that the driver is clearly a stunt driver. That's All.
