Fellow German car manufacturer Mercedes-Benz dropped its entry-level C-Class Wagon in 2004, because “demand for wagons, for all manufacturers including Mercedes, has declined as SUVs have grown,” says a company spokesperson. So the company’s wagons focus is on the high end, with two choices, both in the midsize E-Class line: the E350 4Matic and the E63 AMG. The latter, with its AMG-built, 507-hp V8 engine, is one of the fastest cars, never mind wagons, on the road anywhere. “The E63 AMG Wagon is not only the quickest wagon in America, but also the stealthiest supercar in the world,” says Bernie Glaser, general manager of product management, Mercedes-Benz USA. “With a 0-60 mph time of just 4.3 seconds, it shatters all perceptions of what a wagon can do.”
