From 1902 to 1923, Stanleys were built in Newton, Massachusetts. By the end of 1923, the company went bankrupt and fell into receivership. Stanley continued to struggle as both steam and electric power gave way to the internal combustion engine as the engine of choice relegating Stanley to the history books after 1927.

According to Kit Foster in his comprehensive The Stanley Steamer – America’s Legendary Steam Car, the 30-hp Model Z Mountain Wagon was first offered as part of the Stanley catalogue in 1909. The open omnibus was “designed for stage line passenger and baggage work at resorts.” This Model Z Mountain Wagon can be configured with two rows of seats behind the driver or as a pickup truck. Currently set up as a Mountain Wagon, all parts for the conversion are included in the sale. In 1987, it completed the Great American Race from Disneyland, California, to Tallahassee, Florida. One year later with sponsorship from Culligan Water, it completed the GAR from Disneyland to Boston, Maine, proving its worth as an able tourer. It is believed to be the only steam car ever to be entered into the GAR.

After purchasing the car in the early 1990s, the consignor engaged Stanley restoration expert Daryl Kendall (who, as a very young man, accompanied Stanley enthusiast Carl Amsley on the Great American Race) to restore the vehicle. Following restoration, it was awarded with its AACA First Junior in 2001 and Senior Award in 2002, both in Hershey. Subsequently, it has received several Repeat Preservation Awards. In 2006 the Stanley participated in the Land Speed Records Centennial in Ormond Beach, Florida.

It is listed in the Stanley Registry as chassis no. 5088: “One of Carl Amsley’s many Model Z recreations.” It has been fitted with updated but concealed hydraulic rear brakes for better over-the-road performance and safety. In addition to the lustrous brass trim and brightwork, the car features battleship linoleum floors, a Jones speedometer, and luggage rack with trunk. A complete file documenting the restoration is included and available for inspection. More recently, a new boiler was installed by Daryl Kendall in 2009.
