Coupé, sport, lightweight construction. CSL: three letters that give every sports car fan goose bumps. The BMW M3 CSL is regarded as an icon and the crowning achievement of the third M3 series. What's more, the M3 CSL still occupies the same unrivalled position amongst the various models in that series as it did when it was first launched. With it, BMW M took everything the top echelons of motorsport had to offer in 2003 and once again raised the sports car to a new level.
