Hi postivetennis, yes as dat2kman said i have one as well, i know of 6 in Queensland, 1 in carins and the rest around Brisbane area, of the 6 Qld cars 3 of us are on this forum 260DET, dan280zxt and myself. I recon all up there would be about 15 Australia wide and 1 comes up for sale every 2 years or so on average here if your very lucky.
My car is a very early 1978 car from Japan it was in VGC in and out but I have completely striped her and apart from 2 bad rust spots on the passengers side roof and on the passenger firewall, the hatch was toast as well but i fluked it and got a new all z parts a couple of years ago , it just needs them fixed and sandblasted then pained to a better colour than what was originally, the light yellow of the interior shell that you can see and the maroon /silver of the second paint job. and put back together i have a couple of other z projects on the go so the zx will have to wait for $
I agree with very one elses comments try and source a car from the USA. I would look at a genuine turbo car or even a 10th anniversary model, look seriously at the cost of getting the car complianced here. a lot of American muscle cars are coming to oz at the momnet so shipping wont be an issue but compliancing will be the biggest cost to you , so i would get a definite costing on that,
I have a friend who has just brought a beetle in from the US and the permit to import took over 10 weeks to get so don't believe the gov website saying it only takes 3 weeks.
Apart from that good luck please keep us informed
