The 2003 Mercedes-Benz SLK is a part of the model's first generation. This compact luxury roadster was available with a choice between two engines: a supercharged 2.3-liter four-cylinder with 192 horsepower in the base SLK230 model, and 3.2-liter V6 engine producing 215 hp in the more powerful SLK320. Both models were rear-wheel drive and came paired with a five-speed automatic transmission as standard, though a manual option was available. Interior comforts included leather upholstery, a premium audio system, and available COMAND infotainment system. Safety features included anti-lock brakes, traction control, and stability control. The car is renowned for its retractable hardtop, which could transform it from a coupe to an open-top roadster within seconds.
