Correct, it will never be registered with the original vin of the imported donor car.
Under ICV status, Transport SA here, assign the project a vin number, and it must comply with current emission requirements at date of ICV.
It is the same system one can build a cobra replica and the likes.
A "Statement of Requirements" is issued, and the build needs to be inspected, and signed off by an accredited engineer.
This is certainly the case here, but it may well be different in NSW.
I will most certainly have Prodigy LEGALLY registered by the end of this year. I wouldn't have wasted 7 years of my life, 7500 hours, and a bucketful of money if I couldn't.
It may also mean Prodigy MAY not be registerable in other States, this I haven't explored, but frankly, it is of little importance to me right now. I didn't build it to sell.
In my travels to the Eastern States, I've seen many Vettes that could never be legally registered here. LHD classic cars here need to be 'stock as a rock' or they will never be registered. Virtually, any mods will deem the car unregisterable, unless it is converted to RHD, go figure!!!
Would be real helpful if we had a National system, but that might go against me with Prodigy, so I'll just run with what we got.
