I have no doubt that the ML63 is a capable performer, but in the German magazine Autobild, they tested one and said "That the AMG M-Class cannot go offroad anymore." So why buy a gas-guzzling SUV that can't go offroad? I just don't see the logic behind this. If I want a fast car, I'll buy a fast car, not a fast SUV that can't go offroad anymore.

Admittedly, very few M-Class owners will go offroad anyway...but still...
