The Mercedes SL is a mainstay of the German brand’s range and its flagship two-seat convertible.
Although SL may translate as 'sports lightweight', it’s actually a luxurious roadster that weighs almost two tonnes. Despite that, it’s anything but slow. In fact, it's so quick it's a serious rival for two very fast and upmarket drop-tops, the BMW 6 Series Convertible, and the Jaguar F-Type Convertible.
