I say let's take The Brick, but have the same feeling you do when referring to xB's in general. It's not a car, or a truck or an SUV. The State of Connecticut classifies it as a wagon, but a wagon to me is a Ford Country Squire with vinyl woodgrain on the sides...so I have a hard time with that description. More often than not I end up using generic terms like "vehicle" or "ride".
