It's also illegal to swap vins out like that.

i have phoned the DVLA (thay do licences and car laws in the uk) and gave them the reg and thay said it can be re-regesterd and driven on the road,thay said thay have no problems with that. its just the council and the scrap man who is being awkward. however it sounds like i may be able to buy the car in bits, engine,boady, doors. well i dont mind that atall now i just have to see how much thay want for it?

Depends on the circumstances. It usually only illegal if you are doing it to a stolen car. Anyway, we are talking about 3 different countries here, UK, USA, and Aus. The laws are bound to be different from country to country.

Nissan recalled a bunch of S30's in Japan and stamped X's over their chassis numbers and gave them new ones. I forget why, but that wasn't illegal.
