Depends what the guy wants and how mechanically knowledgeable he is, my 32 has had a few things go downhill on it. i.e. clutch/coilpacks/found some rust
I fixed these issues cheap due to people i know and what i can do myself, wouldn't of been the issue if it was someone else who doesnt know anyone/cant do anything themself.
Down under auto in Wangara has the most mint32 I've ever seen in my life for sale atm, factory weather shields and shit, mats are mint same with paint and that. If your looking at a 32 I'd go buy that one.
He has a Gt-R or two down there as well.
Whilst in Wangara, Distinctive Car imports has a few 34's and 33 GT-R's that are close to your price range.
In reality its hard to know what you like, but as a rule of thumb, the less you know the newer you should buy, also dont get anything with a 26 in it if you dont have deep enough pockets to fix it should the worst happen.
