If you're gonna quote me and post a different class and different car (4 hours - totally different class, RS), allow me to retort with the correct pricing for what I talked about just so that there is no confusion ;-)
Also I recommended avoiding these (done them, fun, but value for $ less good) and getting the carrera S ($725) + cayman GTS ($750) for the same $1500 or so price, 2 sessions for the price of one. I did one session AM, one PM, lunch in between, awesome day and you can use the break to process stuff and relax, it's not feeling too short. I went with a friend and session one triggered a migraine for him, he slept it off and went back 3h later.. I'd argue I had more fun with the Cayman GTS overall because it slides better and sounds better, sliding a GT3 or RS with "those" rear tires is no picnic.
Lastly, just noticed 20% off for CA residents at PECLA till jul 31 !the package above for 2 cars is $1200 only if you're local and book soon.. Wish I could but bad dates for me.
