I've always wanted to do that so bad, they don't have that kind of stuff around here though.
So...reviews of the cars?
Even if you have the opportunity it's not guaranteed that you;ll actually get around to it, up until the age of 18 I had only ever lived in two places, firstly in Silverstone, and then in a two about 5 miles away! yet the only time I've ever been to the race track was to race radio controlled cars!
