Best vehicle for cross country..

SEATING
1. Front seats are wide and deep for comfortable thigh support
2. A deep, wide center console / arm rest
3. Rear seats can recline, for comfortable rest

WINDOWS/SUNROOF/DASH BOARD
1. Dash board is flat, so items / GPS can be place on top
2. Sunroof - for added view
3. Rear windows, fully retract, or nearly retracted for a better view

Misc Items
1. Separate A/C control for rear is nice
2. Err? Higher mileage the merrier, bigger the fuel tank - merrier
3. Direct access to rear cargo (SUV/Station wagen) is good.
