The CLK was available as both a coupe and convertible. It delivered responsive handling and decent steering feedback. While the CLK was fast and comfortable, it was never as rewarding to drive as a BMW 3 Series coupe. The 3.5-liter V6 engine is strong, but the muscular 5.5-liter V8, with its seven-speed automatic, provided abundant performance. Opting for the powerful CLK63 AMG brought a brawny 475-hp V8. The rear seats two in relative comfort for a coupe. In the front, a motorized arm moves the safety belt forward when the door is closed. The CLK was discontinued after 2009.
