You cant be! that would seriously cost a fortune to register and run over there.
I only saw a handful of old cars... spotted (and shot - in the slideshow) a group of old Nissan enthusiasts cars in a truckstop carpark... oh and a Izuzu Billet also...
Isuzu Bellet - I went to tafe with a guy who raced them. I think he said it was like driving a greenhouse but once done up they were ok.
A VL wouldn't be significantly more expensive to rego and run than a 32/33 GTR or a TT Supra. It is just for fun as I live less than 5 mins walk from my work.
I have seen a bunch of older cars since I have been here, probably from living in the sticks. 240zxs, 1960s Skylines/Corollas, heaps of American cars and a bunch of other stuff. Datsun 1200 utes have a cult following - although they were still being manufactured in Japan for a lot longer than in Australia (still being made new in Africa I think - called Blackie).
