I reckon if there's a known problem with the car, then maybe just wait until another one pops up. There's heaps of em around.
I thought 15k was more than enough to buy a decent manual NA R34?
But I think if it was me (well I was you 2 years ago), I would just spend 9-10k on an NA R33, get used to the power and RWD first, trash it, have fun with it, as a first car, then upgrade later on. Whether to sell the R33 and buy a R34 GTT 1-2 years down the track lol. You don't wanna be spending all your savings on the car, then realised you can't afford insurance or alarms or potiental accidents or parts repairs.
PS. that TV/GPS that he mentioned, it doesn't work in Australia lol, and if you want to hook a DVD player to it, thats extra $$
