I know someone that managed to bargain his way down from 21k to 17k for a 33GTR in Brisbane. First time I saw that car I thought it looks like a gtst with gtr kit and the condition is just shit, not to mention it runs like a dog and make weird noises. I'm not saying the one you're looking is dodgy, anything is possible and maybe you did find a bargain.
Like TJ said, if its really that cheap, it wouldnt hurt to pay a bit more to get a full proper inspection done which will probably gonna cost a few hundreds only comparing to your savings.

Just did a search on google for that dealer and founf someone bought his 35gtr here from that dealer. Maybe it pays to PM him.
