The Mercer Raceabout is considered one of the most legendary American automobiles of the Brass Era and one of the United States’ first sports cars. Its large four-cylinder T-head engine and well-balanced chassis combine to make the low-slung Raceabout a competent roadgoing automobile that was also successful at the race track, winning five of the six races that Mercer entered in 1911. This 1913 Mercer Type 35-J is believed to be one of the most original examples in existence and was formerly owned by American Formula One World Champion Phil Hill.
