Since no owner has answered... I took a ride in one on Friday, an SLT 7 passenger version (about $37K). Power is nice, ride is excellent. Fit and finish are on par with much more expensive vehicles. Fuel economy is supposed to be in the mid 20s, but that number is likely to vary greatly.
The thing I like the best is the room in the rearmost seat. I'm 6'1, 270 lbs, and I can fit back there with room for my legs, feet, and head. I'm not saying I'd like to go 500 miles back there, but I think I could.
