For those who were not there last year here is how it was worked out.
On booking in your car is placed into it's class, this dictates how much it will cost punters to have a ride in the car. £60 if memory serves me well for the Maserati.
Track brief followed
couple of recki' laps
The day is then split into 15 min slots, group A, then B and so on. As the day progressess and dependant on demand the sessions become more like an open pit.
Prior to the first sessions you are asked to show [pimp] your cars so punters can see whats comming on track and book a ride if they wish.
You then drive down to the pit, stop in the inspection hall, pick up your passesnger and do your 5 laps...fast or as slow as you and your pasenger wish.
At the end of their session you drop them at the pit gate
If things are slow you can stay out for longer if you wish.
If no one wnats a ride, thn just have a few laps solo and try again, or grab a coffee
I had plenty of time to myself [due to the heavy rain] but it got busy later as the sun came out.
