General Motors recently conducted a program benefitting Habitat for Humanity which was intended to demonstrate how useful SUV's can be. The vehicles were used to haul construction materials around.
Well, that's all fine and dandy if you're building a house. But I'm willing to bet that most of the Ford Excursions and Chrevrolet Yukons clogging our highways are hauling lawyers, accountants, and soccer moms; NOT sheet rock and plumbing supplies.
