Cheers for the bump Terry and Simon, search is still in progress.
Judging by the look of that one, it may one of the old top secret promo gtr's.
A guy named Travis that lives down the road from me used to own it. He sold it then the guy that bought it, sold it here - http://www.skylinesaustralia.com/forums/topic/339442-skyline-r34-gtr-v-spec-imported-by-top-secret-imports/
If its the same car, nice to know its still in Sydney.
