Mercedes is famous for its smooth, solid ride quality, and the E350 doesn't disappoint. This car cruises the highway like a high-speed luxury train. Road noise is kept to a minimum, and the supple suspension would win praise at twice the price. If you do a lot of long-distance driving, the E350 will have you looking forward to every trip. With new headlights and smoother body panels, the E350 is one of those cars that will never look dated. It's got classic rear-wheel-drive proportions with a short front overhang, and that 3-pointed star on the grille will look just as imposing 10 years from now. If you want to tell the world you've got good taste, the E350 speaks volumes. The E350 comes standard with a 3.5-liter V6 that makes 302 horsepower. It's just the right amount of power for this car. Passing slow-moving traffic is a breeze, and the V6 never feels like it's working hard. It won't kill you at the gas pump, either; the Environmental Protection Agency rates the E350 at 30 miles per gallon highway.
