If you participating in the Audi Track Day @ Castle Coombe on the 2nd April, and you are interested in receiving tuition from an instructor, could you reply to this thread

If we get an instructor there for the day, we obviously have to pay him up-front, so it would be good to get an idea of interested people, then we can see if it will be viable...

At Donington we were charged 20 for 20 minutes on track tuition, I guess the figures would be very similar
