Thanks guys for all your replies. Well the car is in and have just had it all checked over by both my mechanic, my panel beater and the compliancer.
Mechanics notes:
Compression 150,150,150,148,150,150
Clutch- basically gone
up on the hoist- Car looks straight, no rust, small leak at gear box (nothing serious he has assured me), claims most of the GTR's he sees has some sign there.
From the panel beater: (he looked it over for nearly half an hour, pulled out a lot of the trim etc) thats what you get when ur girlfriends dads a panel beater
Cant see a sign of any serious repair, Every panel is in line, claims you can see very minimal colour differance from the door to the rear quater however hardly noticeble (front gaurds therefore have been re painted as Jake32 stated). So any major repairs have been done correctly (which from experience is very rare in Japan). All original series 3 parts Xenon lights front bar etc. All airbags original series 3. So i guess if it got hit by a bullet train it must have been going very slow
all in all im really happy with it it is absolutely immaculate inside (bar the shit head unit) and looks great outside, exactly what id expected.
Well it just goes to show how innacurate some of the information can be on Auction sheets (it takes the guys 5 minutes to write them up so no surprises there) and you just have to trust your guy in Japan for his Judgement when he looks the car over. Lucky the guy i use im personaly friends with and one of the most padantic guys that i know, and has been doing this for most his life.
Thanks again for all the info. Now ready to get her on the road and start wasting money on performance parts
