A big thankyou to the OP for reminding me about these events.
I was at Thruxton this afternoon and had a fantastic time, my best moments were getting the VXR8 into 5th coming out of Church up the hill - must have been doing over 130 but I was too busy preparing to brake to really check! Another good one was one of the instructors asking how much track time I had done, my answer being none!
I certainly got my moneys worth, driving the Corsa and Astra twice, the vectra, zafira and meriva once and the VXR8 three times - I love that car. The instructors were really good, helpful advice on the first few runs, shutting up once they know you arent going to kill them and pushing you harder when you are getting the hang of it - slip streaming a vectra in a Zafira with the instructor pushing me faster was fun.
The journey home was slightly less interesting.
