Worth every penny. I did the one day class back in Jan '11 when they were first opening. The guys are ALL top notch instructors. They've modified the program a bit to allow for use of the real rally cars (group N?) for many of the students. I was a little bummed out that when I was behind the wheel, there was many a time I would've dumped the clutch mid-drift to maintain the slide and momentum of the vehicle - but didn't because no one told me I could. Then when Adam got behind the wheel at the end of the day, he was popping that clutch like a pock-marked teenage boy.

That said, a local rally guy by the name of Scott Kovalik just signed on with a multi-racing style instruction school in Florida. Scott was racing in the Rally America series with a Lancer Evolution. http://www.facebook.com/MotorsportHeaven
