I went to one a few years back and drove an R8, DB9, Gallardo and Murcielago. I enjoyed it but the only annoying thing was that the instructors would tell me to shift at 4-5k revs.
Speaking to someone else at the same track who was driving a 360 Modena, he was allowed to rev it a bit, but then drove a 458 and had to change early. Think it is something to do with the age of the car and the instructor you get really. Still worth going though!
