Moss's first World Championship victory was in the 1955 British Grand Prix at Aintree, a race he was also the first British driver to win. Leading a 1–2–3–4 finish for Mercedes, it was the first time he beat Fangio, his teammate and arch rival, who was also his friend and mentor. It has been suggested that Fangio sportingly allowed Moss to win in front of his home crowd. Moss himself asked Fangio repeatedly, and Fangio always replied: "No. You were just better than me that day." The same year, Moss also won the RAC Tourist Trophy, the Targa Florio (sharing the drive with Peter Collins) and the Mille Miglia.
