The best place to race cars in Las Vegas. Hands down. I was super apprehensive to drive fast because I didn't want to kill someone else or myself. But the instructors were super supportive; they actually wanted me to go faster than I did! My guy (JT) was money; if there's a way to request an instructor, you'll want to get him.
In addition, this is one of the few facilities where the instructor (who is in the car with you the whole time sitting in the passenger seat) doesn't have a brake they can press when they want you to go slower.
By the way, I drove a Ferrari 458. If you want something street legal, get that car. You're welcome.
