If she's looking at SUVs specifically for posture I'd recommend checking some of the small two-box cars out there now too like the xB or PT Cruiser. Much better on gas, easier to maneuver in tight spots, easier to get in and out of, lower center of gravity, etc. Not the most stylish of vehicles but far more practical. I didn't like the driving position of the xB (felt like I was in a school bus!) but the PT is surprisingly nice - a friend just bought one to complement her parents' two.
If the car is totalled, of course.
