I would recommend Bondurant over this. In 3 days at the advanced course I had about 16 hours of track time, and every time I wore out a car they had another waiting to go. Plus I see my instructors on Speedvision doing well in various race series.
Bondurant is probably the best out there, until BMW gets their's up and running!
This did look like a lot of fun just the same. Don't really think you would take anything home from this other than the experience of doing it. Unlike the training you recieve at Bondurant, which translates into everyday life and road conditions.
