Mercer was known for building some of the best sports cars. The Mercer Raceabout (1911-1915) was one of the premier racing cars of the era. It was highly coveted for its quality construction and exceptional handling. The car’s original design was conceived by Mercer’s general manager – and society playboy – Washington A. Roebligh II. Roebligh perished in the 1912 Titanic disaster.

The engineer of the early Mercers was Finley Robertston Porter. He left the company in 1914 to build his own car, the F.R.P. You can find the only remaining F.R.P. in the world on display at this museum.
