Yeah but the queston you asked was"what should I get an R34 GT-T or R33 GTR and which is better" So we all assumed your buying one. Driving on a farm or driving low powered cars isnt going to help you. Its when all your mates pressure you into doing something stupid and you wrap it round a poll is the issue.
My advice dont be in a hurry to grow up. Buy a clapped out bucket of pus and drive that around till you understand the road rules and other peoples driving habits. Sometimes its not yourself you have to worry about its other drivers.
