niZmO_Man and warps are on the money, Combine the two and you get R31 track car. Cheap, fun, fast enough.
On a more serious and grown up note, dont spend your uni days partying and boozing up. Once you start failing units and end up incurring a bigger HECS debt than you planned, then your GTR and other plans will be pushed back. Get an R31 for track and keep the camry as a daily,
