Heath,
I'm sure if you ask someone from here in Vic to come with they will. If I can make time I'll come with you just PM me. I remember seeing that that carizma GTR before we bought our's over 9months ago... so that could explain half the story.
Finally, if you think you've found the right car I would recommend taking it to Ben @ racepace or ICE Performance. You really need someone who knows there GTR's and not just any mechanic.
Dunno about everyone else, but I always question cars that have been resprayed, especially different colours. There's an R34 GTR Vspec in QLD for $65K..?? way too cheap, fully resprayed Nismo Blue. I called a mate who knows the industry more than anyone and was told the to stay away as it's been a damaged fix job. Hindisght's a funny thing, I nearly bout an SAU forum members Silver R34 GTR with mega mods, until I called my mate... he gave me a list of problems and damage longer than "Sandown Straight", which was confirmed by Ben from racepace. The car is now for sale at a well know *cough* reputable Import Dealer in the city.
All in all, import or not, it's just a matter of working your way through the crap and with some patience you're sure to find the perfect beast. Unfortunately (I was the same) you assume all GTR's are worth that much, but more than likely there's a hidden reason behind so called bargain price.
