Boo, both Captain Russ and I have had excellent service from Scion XB. It has plenty of room for big people and lots of gear, gets 34 MPG and doesn't cost a fortune.
Only thing, mine is from a few years ago, and probably would be under-powered for mountain driving. The newer model has a bigger, Camry, engine and would be better for you.
Susan has now commandeered the XB and I'm driving a Ford Expedition. Wow, what a difference in gas mileage. I can get 16 in town and maybe 21 on the highway if I'm careful.
