LOL - the word "responsible" exists in car enthusiasts? If it did, you wouldn't have a Skyline.
Nah, James - just save up like $50 a week till the track day (still 2 months away) by then you "should" have $400.00 to play with. Not much, but it helps...
Least you don't have to get your car sorted out before this event; I still got to squeeze in a tune after my fuel upgrades... add onto this about $1k worth of parts for my other car
