A Mercer Series 5 Raceabout — the two-passenger, open-top sporting model that represented the pinnacle of American performance motoring during the Nickel Era — this example spent its early years in Venezuela, owned by a general under the Gomez regime, accumulating just over 14,500 miles. Discovered there in 1967, it was brought to the United States, where a meticulous multi-year restoration was carried out, and it passed through the hands of several dedicated enthusiasts before reaching its present owner. Original Venezuelan registration and engine and chassis stampings support its authenticity.
