Get a skyline! haha. In that price range you could get a R34 GT-T sedan with well under 100,000km. also check carsales.com.au, drive.com.au, carsguide.com.au etc. dealers are ok if you want a warranty etc, but u might not find them with the mods ur looking for..private seller is probably more suitable. good luck with finding what your looking for man.
