Heh, several months ago I was on a business trip and we rented a Nissan Armada. Compared to our humble minivan, it carried fewer passengers, was less comfortable, had maybe half the cargo space, got worse gas mileage, and handled worse. Ok, so it has better ground clearance (yeah, how many owners actually use that?) and more towing capacity (3,500 lbs vs 3,000). But it did have a nifty camera setup, and the in-dash display would show a cool 360 degree view of the area around the car whenever you backed up!
Suburbans are a bit better on the comfort and cargo space front, but that's about it.
