I recently bought an EVO 7 from NSW. I drove 45 mins across Brisbane to go to an EVO "specialist" for RWC, he told me: under 90mm at one point, POD filter illegal (had top be boxed), tint on rear windows too dark (factory tint) and carbon boot were all no no's. The carbon boot was to be expected but the rest was a bit over the top.
I took it to the local mechanic 5 mins down the road from my house (he knows nothing about imports) after changing the boot and he passed it without blinking, I was in and out in 10 mins.
The point is choose the mechanic carefully, some are overly anal. If you have some sort of a "relationship" with a mechanic who has done work for you previously, try them first.
Re: QLD transport, they didn't even look at the car let alone engine and VIN numbers etc. It's luck of the draw I guess.
A REVS check should cover you for stolen and encumbered vehicles but make sure you don't purchase it until just before you hand over the payment as they are only valid for 24 hours
As far as transport, I drove mine back but I enjoy long drives so it's a personal thing. I'd say putting it on a transporter would be more expensive though and I have visions of some transport monkey burning out the clutch driving it onto the truck or doing limiter launces and helis in their carpark....
