Stirling Moss and his navigator Denis Jenkinson piloted this 300 SLR to victory in the 1955 Mille Miglia in a record time which has remained unbeaten to this day. The cars left the start line in Brescia at one-minute intervals – car number 722 stood for the start time of 7:22 a.m. The success of the 300 SLR ensured that Mercedes-Benz would have the 1955 sports-car world championship title to add to its triumph in Formula One.
