It started off in the M3s which were surprisingly fun.  The steering had a good weight, but some of the drivers were taking it *very* easily.  So slow there was a queue of about 6 cars doing 30mph at one point, slower than they'd probably drive in their road car.  Still once I'd cleared the traffic I had a good run and overtook Rob just before the chequered flag at the end of the session.

The single seaters then followed which were former Palmer Audi cars.  They would have been great in the dry but in the wet I really didn't feel like giving it beans plus they were rev limited on the straight which was really frustrating.  

After the session ended we had a debrief and then Rob had a few passenger laps in the instructor driven JP1 which judging by the grin on his face when he stepped out, was quite enjoyable :)
