Im also with my NSW rego here in Adelaide, and they ask me to take the car to a Vehicle ID Inspection to make sure it wasn't stolen or something, this is to transfer the car to a SA rego, it was done in Regency,
took the car there and the car didn't pass the test.......No it is not stolen that was all good of course but the guy didnt like the window tinting, I asked him is there was anything else I would need to fix or get done he said no, thats it come back when you get rid of the window tinting and you are done!
I have Tein coilovers, BOV, HKS Pod, 3"Exhaust, 17" Wheels, the car is very low, but they didn't seem to care about this.
So it all depends on their mood really, unless there is another test I need to pass before I can transfer my Rego, and im unaware of. uhmmm. no good.
