[at-l] Car for camping

[giniajim]

I'm starting to look for a "new" car.  Along with all the usual attributes, 
I'd like one with fold-down seats that I could stretch out, put down an air 
mattress and air mattress, and sleep in.  I know (or think I know) that cars 
like exist (but can't think of any specific brand right now).
    For the purpose of this question, not looking for a pick-up truck or 
mini-van.
   Has anyone used such a car and have any recommendations or suggestions.
Thnx!
