Looking like a stylish coupe but in reality a four-door sedan, the 2006 Mercedes-Benz CLS500 is a stunning offering from Stuttgart. Seating is limited to four passengers due to the individual bucket seats in the rear of the car, but given the close quarters, you wouldn’t want more on board. Radiating a sense of luxury combined with the sexy lines of a sports coupe, the Mercedes CLS500 is powered by a 5.0-liter V8 producing 302 horsepower.
