Chris,
You're right. He is a very cluey man, with a genuine interest.
And it is with many thanks to Trevor that, YES, i am driving the GT40 around now.
My time is being chewed up ATM by the Elise/Honda. My co-driver crashed it at eastern creek in the last ProdSports 1-hour. I'm sprinting next weekend, and pushing $hit uphill to get it right in time.
