The Company

One of hundreds of Michigan-based auto manufacturers in the "brass age," The Alter Motor Car Company was located in Detroit, with its factory in nearby Plymouth. Alter produced over 1000 cars from 1914 to 1916. The company went into receivership and closed its doors in January of 1917.

The Car

The Alter was designed by Clarence Alter of Manitowoc, Wisconsin. The car was made from component parts shipped to Plymouth by rail for assembly. Two models were produced, a 5-passenger touring car and a roadster. Only one Alter is known to have survived.

The Factory

Built in 1914 for the assembly of the Alter car, the factory stands to this day on Farmer Street in Plymouth, Michigan. It war recently refurbished and is currently the home of the C.D. Sparling Company.
