They are available, but hatchbacks are quite common and you wouldn't want the sales staff remembering that you insisted on paying more if need be for a larger model with an enclosed trunk.
The Renault Scenic does have a built-in partition that you can snap in place over the trunk space - to prevent smash-and-grabbers from seeing what you have in your trunk.
Thanks. Good point. It still seems to make the scenario the police are laying out more unlikely. Actually, I’m on the fence on this one. I think they have acted somewhat suspiciously, but I thought the same thing about Chandra’s mother. People act differently under grief and stress. But I don’t see the professionalism from the police I associate with credibility, either.
