Had an amazing time at Exotics Racing in Las Vegas! The driving instructors were all great and seemed to really enjoy their work. I had booked two cars, the Porsche Cayman and the Mercedes AMG GTS. About a week before my appointment, Exotics contacted me to tell me that the Mercedes would be down for maintenance, but they replaced it with the Audi R8 V10 and gave me an extra lap. Wish I got the time in the Merc, but was very pleased with the Audi. The staff, behind the counter seemed a little annoyed at everyone though. Not sure if it was because they were all pretty young, or why, but that would be the only real negative I experienced.
Overall, it was a great time. You'll need to save up, but it's worth the experience.
