I have signed up and payed.
But the more i read, the more i too am getting a little anxious!
I dont want to hit a wall as well as i have just forked out $250 for a set of rear tyres and just realised i am going to be chewing 50% of my fronts as well!
On top of that, to sum it all up. Its going to cost me about $470 just to attend and enjoy the day, that doesnt include extra oil, coolant, petrol and food.
So for 1 day costing over $500 its quite costly and as everyone else has said, this is the main reason i wont attend very offtern.
my 2c.
