Because I doubted, as I have written various times, that Holden would have gone to the expense and effort of using a one-off fabric in the run of the mill Commodore.
Also, I don't believe I have stated in my discussions regarding the Calais that there was a Calais station wagon. If you take the time to go back and reread all of my comments I started off by writing that I believed it possible that CG may have been witness speaking to someone driving a station wagon, said no thanks or whatever, then continued on her journey back to Mosman Park, and then another driver, perhaps driving a sedan Berlina or Calais has abducted her.
You're starting to sound a bit like Bart lol !
Thanks for clarifying.
I'm sorry but I believe your conclusion that the vehicle was a Berlina is incorrect. It may well have been a Berlina, but you cannot conclude that from your hunch.
If you look through the history of the Holden Commodore it started with vinyl seats and today has something totally different. Often between model changes, such as from the VR to VS Commodore, Holden would change fabrics or colours to make the car seem different to its predecessor. A fabric colour or texture change was more likely to occur from the VR to the VS as the body shape didn't change (Holden needed a point of difference somewhere else on the vehicle).
It's likely the fibre match is colour based rather than fabric type - or it could be a mix of both.
So yes, colour wise and forensically, Holden would have gone to the expense and effort for a one-off fabric in the VS Commodore.
