Well there was a gold coloured skyline that was down from vic, visiting his family for a while and he got defected for his T wing. Ive heard of numerous cars from vic being defected here and like wise in vic.
I also went into motor and reg and asked them, as i am taking a venture to melbourne soon. They said that u can be defected but the info takes a while to get to adelaide.
It all depends on wat u were doing and the cop u come across, kind of like in our own state.
I may be wrong but its wat ive heard and seen.
