The Mercedes CLK is a mid size luxury coupe range that was launched in 1997. It was discontinued in 2009 when the range was returned to the E Class name that it held previously. The vehicle holds similar styling to the E Class model as well as engineering that is based on the C Class model. With an attractive design and appealing styling, the range attracts a wide audience, helped no doubt by the premium badge. The range is available with petrol and diesel options, although the diesel is the best all round option. The 270 CDi diesel motor is incredibly supple, delivering excellent refinement and a smooth driving experience. In all, the Mercedes CLK is a premium range that offers impressive efficiency and luxurious styling.
