The CLK-Class is the two-door coupe or convertible based off the C-Class. Unlike other Mercedes-Benz droptop models, the CLK-Class features a fabric roof without sacrificing exterior design or interior comfort. The CLK 63 AMG ups the ante with sport-tuned suspension and brakes, unique aerodynamic exterior modifications and 481 horsepower under the hood. The CLK-Class comes with a four-year/50,000-mile warranty and gets an estimated 20 mpg on the highway.
