I can definitely recommend Aussie Car Compliance: http://www.aussiecarcompliance.com.au/cars4sale.htm
I bought my car off Joel and it has barely missed a beat. The cars they sell are top-notch, not too thrashed (visibly, but I bought my R33 GTS-T with 55,000k's and engine compression tested at 150psi across all cylinders (ie. very good!))
Plus all cars come with full 12 months rego, and 12 months warranty.
Dont trust the website, it hasnt been updated for a while. Just call Joel and tell him what you're after. If he hasnt got it, he'll certainly be able to bring it in and compliance it for you. I got mine straight from japan and somehow managed to be complianced even though it had an aftermarket turbo/computer and supporting mods. Supposedly they should be brought back to stock, but I have my suspicions
