even parts for common Nissan sports cars like 350Z's and S15's are imported from japan. Only limited stock is kept on hand in Australia, and is shared by spare parts divisions.
Agreed that factory servicing depts will be given specific training on the new GTR, but with a performance car, the factory warranty is voided within a few months of owning the car... and workshops dedicated to servicing performance cars are, in my opinion, much better equipped to work on a 300hp+ car than a mechanic who also has to tend to Nissan X-Trails and Tiida's.
The insurance premium for a locally sold S15 is the same as it is for a grey import. back in the day a few years ago the origin of a car and the availability of parts played a big role as Australia was somewhat isolated from the rest of the world, and for example, repairs meant things had to be ordered in and took forever. These days in a global market which is forever bringing us closer to the rest of the world this isn't an issue. Insurance companies are wise to this now and adjust rates accordingly.
If you've ever read the R32 GTR FSM that was supplied to australian workshops and the FSM that was delivered to japanese workshops you'll notice a world of difference, the detail is simply mindblowing in the latter. Nissan might as well have given australian mechanics a chisel and a hammer to fix the GTRs. Plus you'd think if the GTR was to be delivered to countries like the UK and US they'd have it in english anyways
This one I agree wth, I was quite impressed with the ADR approved turbo/supercharger kits being developed for the 350Z. However, being a global car, the big bucks are in R&D in the US, UK and Japan... so I'm fairly confident if bolt on kits and quality aftermarket parts are to be sourced, they'd come from these countries.
