The 2006 Mercedes-Benz R-Class is a luxury crossover vehicle offered in two trims, the R350 and the R500. Built in Alabama on the same platform as the new M-Class, the R-Class will offer three rows of seats inside an interior designed to be spacious for six adults. As yet another luxury crossover option in a crowded field, the 2006 Mercedes-Benz R-Class is one that will either go a long way toward improving Mercedes’ fading reputation for quality (see: Consumer Reports) or fall by the wayside, just another forgettable crossover compromise. It matters because of its styling and Mercedes-Benz technology, such as a seven-speed transmission, matched to three rows of seats and what officials tout as a spacious, well-designed interior.
