Even my wife couldn't sit up straight in the back. The Mazda CX-9 is seriously luxe, but with the "agressive" profile of the windows, the back seat feels like the navigator's seat in a cockpit. IOW nice and roomy, but still claustrophobic.
The surprise (to me) was the Mazda 5. Seriously. Three useable rows, sliding doors, but looks and drives more like a wagon than a van. If we weren't anticipating trips with the kids and a set of grandparents, we'd probably be getting one. But the storage space doesn't come close to the vans.
