I do, well used to.
Not car, but motorcyles. Dad races his specialised Nortons and i used to race a 80cc Kawasaki (proper long, raked forks, 14 sec quarters etc).
Will be doing some more later on this year, but I will be riding my own Norton (which I have to build up :- ). So that should be fun :lol:
We used to reguarly go to Santa Pod and Avon Park, occasionally got to see some of the super quick motorcyles testing there, they are immense.
