They're going ok currently. Yes, the supercar club allow their cars on track - they even organise the trackdays on your behalf. Doesnt get much better than rocking up at EC, getting in the 997GT3 for a few laps, lunch, then the 360CS or F430 (or exige S, or whatever you like) for some more laps later on in the day!
Bargain of a club - and all the guys that work there are (very busy 24/7, can never answer the phone) deadset legends
