Hey mate,
I'm on my P's and I own a R33, I did what you are thinking of doing and learnt that lesson of buying a car with no money left over the hard way...
Had it 2 weeks then got T-Boned, still paying it off and that was 9 months ago!!!
Have you checked in2 insurance costs with the R33 cause I was paying about $4500 for it, dont know much about the R32 prices...
And no matter wat you say about being a safe, curtious driver, all that changes when you get a high powered car - its impossible to deny the urges!!!!
I couldnt give you an answer on what car 2 buy, its personal preference you've got 2 make up your own mind on that, but gotta tell u that my car has had a few problems which I'm still trying to work out but not once do i regret buying it!!!
I know re-sale values are dropping at the moment, and will more than likely be pretty hard to sell if they bring this V8 and Turbo restriction in on P Plate drivers but wat do u do...
And with the parents thing - mate, they all do it... My parents over-reacted, with the whole buying another car thing, guilt trips, and I told u so's, but they give up eventually!!!
Hope this has been a help - goodluck with it all...
Cheers.
