  Title: Ann Arbor (automobile)
  Passage: The Ann Arbor was an automobile manufactured in Ann Arbor, Michigan, by the Huron River Manufacturing Company from 1911–12.  The Ann Arbor was a dual-purpose vehicle, which could be converted from a private car, to a small pickup.  Automotive production, however, never succeeded in Ann Arbor.  The ill-fated Huron River Manufacturing Company, later the Star Motor Company, did not survive the fierce competition of the burgeoning auto industry.  The high cost of living in Ann Arbor meant higher wages and the distance from Detroit increased the cost of materials to a point where profit disappeared.
