I was considering going if I could get my car serviced in time, but that's not happening till next week (also finally getting phat bushes installed that have been sitting in my room for 3 months
)
I'm just going to the OzLiberty meet instead now, apparently close to 30 people are going....dunno how they got that figure though seeing as only like 12 people have posted in the thread for it on their forums.
If you're confident your car is in good shape I don't see why you shouldn't take it to the track, sounds like a lot of fun.
