Mercedes' 'W194' endurance racer left an indelible mark on motorsport in 1952. winning Le Mans, the Nürburgring Eifelrennen and Mexico's Carrera Panamericana, and it finished second on the Mille Miglia. It was retired after only a season, but such was the interest it caused that Mercedes' US importer Max Hoffman (who would later prove key in the genesis of so many Porsches) suggested Mercedes should make a production version. So it did: in 1954, there followed the 'W198' 300 SL 'Gullwing'.

Six further generations of what would become known as the Mercedes SL followed, the longest-lived remaining in production for a remarkable 18 years. But over the decades, the SL has been defined very differently, swinging all the way from motorsport exile to thick pile-carpeted, gently wafting, drop-top luxury icon.
