To most consumers, touting its four-door masterpiece as a "coupe" makes little sense, but one cannot argue with the sheer beauty that is the newly improved 2009 Mercedes-Benz CLS. With its stunningly sleek profile and lavish four-passenger interior, the CLS is clearly not your run-of-the-mill luxury sedan; it's a car equally adept at satisfying both the driver's senses and ego. The CLS' head-turning good looks are backed by two engine choices, including a supercharged AMG creation capable of generating an eye-popping 507 horsepower. For the well-to-do who seek a vehicle as dynamic as it is expensive, the Mercedes-Benz CLS ranks among a select few that can truly be called "exclusive."
