The first generation ‘Sportlich, Leicht 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 3.2-litre V6 version, and a high-performance AMG version, the SLK is one of Mercedes-Benz’ best known, and most sought-after, models.
