The car was donated to the Nevada County Historical Society in 1947 and was placed on display in the Firehouse Museum in Nevada City.
During a remodel of that museum, the car was removed to a garage on Main Street and stored in the attic with the Cal Palmer carriage collection. In 1999, the car was again moved, this time to Terry Horlick's garage on Miner's Trail, about one block away from its original construction site on Race Street.The steam plant was missing so the engine was converted to run on oiled compressed air.
A "Centennial Drive" by Dr. Horlick on October 21, 2001 recreated the vehicle's first steam powered outing of a century before.
The Jeffery Steam Automobile is on permanent display in the museum.
