Just an idea, if your trying to sell it maybe take it down to AJM at Kangaroo Point/Gabba and ask them to sell it on consignment, but I wouldnt sign anything in case the car sits there for too long..
We did that with the Pulsar GTIR and got a shitload of interest, way more than car sales. But in the end it was carsales that sold it due to the lower price that wasnt marked up by the dealer.
For the record, the v8 r33 is a truly awesome machine, and i'm glad your keeping it. Theres heaps of 33 v-spec owners in Australia, but with the v8 you have a truly unique car thats ball-tearingly quick and probably way more fun than the gtr because it can do skids...
