His own French-made car was noisy and uncomfortable, so the British engineer designed and built a car of his own in his Manchester workshop. It was the best-engineered car of its day; onlookers marveled at how they could balance a coin on the edge of the radiator while the engine was running. One of the curious was a leading British race-car driver who owned an auto dealership and who offered to sell any cars that the engineer could produce. Three years later, in 1907, Charles Stewart Rolls sold the first of the famous Silver Ghosts made by Frederick Henry Royce.
