I got to drive each car for ~30-40 minutes each. As my wife was in the pass. seat.
There's a Jaguar "pace car" front and rear, and everyone is connected with walkie talkies, and the Jag's control the speed and flow of the drive. Trust me, I doubled the speed limit a few times.
What was awesome was we chose the last Red Rock Canyon tour of the day, and although we we shuttled out to the RRC Resort and Casino to start the drive, the cars needed to be drive an extra 18 miles back to the Wolrd Class Driving showroom. And I was in the Lambo when we headed back, so an extra few miles in a Gallardo.....I was mildly amused.
