I think the key words are "won't get caught". Those who rebody a car are as you say effectively breaking the law as you are removing the ADR plate, but how do you repair some cars otherwise? You are breaking the same law by removing the ADR tag to fix rust! Other illegal things happen every day too like lowering a car, running extractors, rebuilding an engine to anything other than standard. It only becomes fraud if you try to hide something. You just have to be honest in how you advertise it for sale (if you sell it) and don't tell any lies, so either advertise it as a van or ute (don't mention Sandman) or be honest it has been rebodied. Then you have no issues with the recent Victorian court case precendent. The problems happen when you misrepresnt a car when you sell it. If you don't sell it there are no legal issues at all. And there is no reason why that white van couldn't be reshelled and win Concours. If done right with the right shell no-one would ever know. It'd be better to see it with a new body than botched up trying to repair rust.
