I ended up buying locally as after crunching the numbers I realised I would have to realistically add more than $5000 on top of my purchase price of a modified GTR to have it pass the pits and regoed in WA.
If it's a very special low km, stock R32 GTR you're looking for, it may be worthwhile. But if you're just after an average condition GTST for under 10k, I'd probably just wait for the right one to pop up locally.
