GMC Acadia. It took us almost 2 weeks to track one down but we managed to get one through a broker, called CU Auto Advocate. (We've used this palce to purchase 3 cars so far.)
The Acadia is referred to as a "crossover SUV" (whatever that means) and it is not as large as a Suburban or Expedition) but does have a 3rd row seating. The one we ended up getting was a Black exterior, charcoal leather interior that is fully loaded; not by choice, but it was the only one we could find get. We tried to make a move on several other Acadia(s) that were more stripped down but every time we went to "lock" into them for purchase, the vehicle was already taken or spoken for in some way or another.
Besides 3rd row seating, our Acadia has navigation, DVD, tow package, 19" wheels, remote start and power everything (power rearview windows, rear hatch, sunroof, you-name-it). This vehicle is by far the most elaborate and sophisticated one we have ever owned. I would say this is probably a bit too much for what we would need but the extras are kind of nice, I am definetly not complaining. Oh and the gas milage isn't too bad - it's rated to get 16 in the city and 22 on the highway.
This will definetly be nice for our drive to Priest Lake, Idaho for a family reunion at the end of the month.
