Most buyers who select the 2007 Mercedes-Benz ML63 AMG will do so simply because it’s the most expensive one in the lineup, so therefore it must be “best,” which means all the neighbors and professional colleagues will envy them. These people have no intent of exploring the ML63 AMG’s performance boundaries. Other buyers might think they’ll whip down a favorite road in this rig, but will soon discover that perhaps a Dodge Magnum SRT-8 might be a better choice. The rest will be loyal AMG customers who want all-wheel-drive for inclement weather.
