I would never get the 3rd row. It isn't a practical third row, it is a third row for the marketing geniuses so they sell the vehicle to people who really need a minivan.

Lose it, and gain a storage compartment and a spare tire.

Reports are floating around about a stretched X5 (X7) with a real third row in the next few years, after the X6. There is also the V series on the drawing boards, more of a people-mover style than the X.
