Heed the warnings! I moved to Oz and was going to import my 164QV. I sent in all the documentation. I just got back a terse note saying that I hadn't demonstrated that I had owned the car for 12 months prior to moving. I had supplied everything possible (including registration papers showing ownership for over 12 months).
My view is that Oz bureaucracy may officially allow car imports but because they don't really want to allow them in so they just make it difficult.
My sister who did manage to import a car wanted to trade it in and the Car dealer offered 25% of the equivalent Oz car.
I gave up and moved back home!
Thanks, I also asked a few friends of mine that moved to Aus recently, they did mention it is difficult and is not worth it. I guess I can always get a Spider that side.
