* Porche SUV - huh? Doesn't do either job all that well.
To be fair: A SUV does only one job well, and that is aggrandizing its owner, and the Porsche SUV is perfect for the job. If it was for the smooth ride at long distances, each car can do better, for less fuel. If it was for the space and driving position, a van would could do that for less fuel, if it was for the loading and hauling capacity, a truck would do better with less maintenance required, and if it was for the offroad capabilities, each dedicated 4WD would beat it hands down.
All a SUV can is telling the world, that you don't want to drive a van or station wagon and will pay a premium not to have to.
