Postwar, Fairman's reliable and dogged driving attributes saw him achieve many successes in sports car racing, particularly in endurance events. He drove for a number of top-rank teams during this time, including Bristol, Jaguar, Ecurie Ecosse, and Aston Martin. It was with Aston that Fairman won his most significant events, partnering Stirling Moss in the 1959 Nürburgring 1000 km, and Tourist Trophy at Goodwood. He also made a brief Formula One debut at the 1953 British Grand Prix, driving and retiring an HWM 53.
