The first generation 'Sportlich, Leight und Kurz' - or SLK - was Mercedes-Benz' take on the compact roadster format. Hugely successful from launch, and selling well over 300,000 models, it rapidly became the main competitor to the models of other major German marques. Offering a wealth of options, including a unique 'Vario-roof' folding hard-top, supercharged four-cylinder engines, a V6 version, and a high-performance AMG version, the SLK is one of Mercedes-Benz' best known, and most sought-after, models.
