2007 Mercedes-Benz S-Class S 600

The 2007 S-Class is Mercedes-Benz's flagship sedan, the car that sets the tone for the entire luxury segment. It drives with a composed, planted feel that makes long highway miles effortless, though the big wheels can be hard on rough pavement. Inside, the cabin is a showcase of luxury, with comfortable leather seats, a massage feature for front passengers, and an ambient lighting strip that wraps the interior. Owners report few major issues, with the most common complaint being wheel damage from potholes on the larger rim sizes. The S 600 trades the S 550's V8 for a 5.5L V12 that produces 510 horsepower and 612 lb-ft of torque, making it the smoother, more effortless choice for highway cruising. A five-speed automatic sends power to the rear-wheel drive, and the big V12 delivers its torque with a seamless surge that makes the car feel lighter than its 4,895 pounds curb weight. Fuel economy is a trade-off at 13 mpg combined, but the S 600's standard air suspension and massage seats make it the quietest, most relaxing way to cover distance.
