It was a small class of around 10-12 people with 3 instructors. You partner up with someone in a X5 4.4 and just test that baby to the limits, more in line with the safety features, such as braking, handling, etc...
What impressed me most was the handling and braking. The X5 definitely out handles and out performs many other sports cars out there.
It was also nice to see all the M5, M3, 330, Z8, X5s all the vehicles at the center. I was drooling the whole time.
I definitely would recommend taking this class, it's fun, very fun, yet informative too.
