The Mercedes-Benz SL55 AMG (R230), produced from 2003 to 2008, represents the pinnacle of automotive engineering and luxury design. With its M113K 5.5L supercharged V8 engine, producing 493hp and 516 lb-ft of torque, this model is not just a car; it is an experience. The SL55 AMG is equipped with a retractable hardtop Vario-Roof, enhancing its versatility and driving pleasure. As an iconic piece of automotive history, this model showcases the meticulous craftsmanship of Affalterbach, where each engine is hand-built and authenticated with a signature plate.
