Point of an ML 63?

[John Doe]

I saw an ML 63 (the AMG--maybe I read the #s wrong) going after a Porsche Cayanne (turbo) and vice versa yesterday, and had to wonder--what is the point? My wife agreed that the AMG ML looks like any other minivan. The vehicles are equally worthless as four wheel drives (except snow and desert driving maybe), but at least the Porsche is good looking. How much are the ML 63s?
