With this confirmation about the car, I thought I would check over the Highgate/Northbridge man Con Bayens mentioned. From what I can find, his Commodore was ex police (bought at auctions) but was a sedan. If the reenactment is anything to go by, it also looks like it's a VP series. He was pulled over in 2002 so car would have been 8+ years? I'm not convinced it's the same man...Questioning why someone would downgrade their car unless as someone said, he had access to the wagon, and was not the owner.
I always thought it was Morey but this description of the man in this book suggests otherwise. But certainly is food for thought in that he may have had that presence about him that convinced the girls that he was trustworthy.
