Called the Cooper 500, this car's success in hillclimbs and on track, including Eric winning the 500 race at one of the first postwar meetings at Gransden Lodge Airfield, quickly created demand from other drivers (including, over the years, Stirling Moss, Peter Collins, Jim Russell, Ivor Bueb, Ken Tyrrell, and Bernie Ecclestone) and led to the establishment of the Cooper Car Company to build more. The business grew by providing an inexpensive entry to motorsport for seemingly every aspiring young British driver, and the company became the world's first and largest postwar, specialist manufacturer of racing cars for sale to privateers.
