Similar story happend over here. Somone had a unlicenced kingswood shell (might have been a monaro, I dont recall exactly) in their front yard. Dont think it had a motor even. Needed a complete restoration. So somone decided to do a complete restoration, new paint, V8 engine, interior, etc. Problem was they stole the shell from the guys front yard and used the chassis to restore. The cops got suspisious when the restored car was presented for inspection at the licencing center. Dont remember why exactly, I dont think the article said. Maybe the chassis number was covered over. Anyway the cops did some detective work and found that it was the stolen shell, so the newly restored car was returned to the rightfull owner. Not bad eh? Leave a junker in your front yard, get a fully restored car back a year later.
