Hey mate nice thread. I'm hoping to do the same thing myself... but hopefully to an 07 model. Just be sure you know what you're getting into... like other's have stated, you could buy a gtr for that kind of money, but you won't end up with something that quick...
I've decided on a Z as I wanted a good looking, modern luxury sports coupe... something that was relatively new with 2 doors, leather seats etc. but could still give me the same if not better driving pleasure I get from my R33 gtst...
There seems to be quite a shortage of contenders with the above criteria... you either have hot hatches like the golf gti or r32 or your left with the RX-8, Monaro or the V35...
