i may b selling mine in a few months series2 $18000
there are a few GTS skylines around in Perth if you find a private sale you could probably bargain it down 2 $13grand but id say you mite need a bit more for a decent one most of the ones ive seen in the newspaper and autotrader have been around the 15 or 16 grand range
you could import one but i dont think itll b worth it you wont save much. i imported mine almost a year ago and didnt end up saving as much as i thought i would but if you want a newer one then impoting may b the way 2 go???
