im 19 iv owned a r33 gtst ever since i was 17, yeh they are an awesome car to drive but very dangerous as well, especially in the wet.
but any rear wheel drive car will be like that, it depends on the attitude that you have towards driving, as i have been reading this topic, i suggest you stick with a non turbo, but get something that still looks nice like a bmw, or somethin that has a bit of power but not too much.
i have lost a few mates in car accidents, and i have learnt from it that it simply isnt worth speeding anytime, there is no such thing as safe speeding, even if there is no one on the rd it takes a split second for something to jump out in front of you, or even something like your tyre to blow out.
by the attitude that you have, i think your parents are right just get a non turbo and do some exterior mods, casue if they have seen you speeding and you sayin u can safe speed, then most likely you will speed and then you will be bitching about losing your license or you wrote it off.
thats just my 2cents
