Williamson-Willey Pontiac (later Doug Willey Pontiac) was a Pontiac automobile dealer owned by John Williamson and Doug Willey. In July 1960 they cut the ribbon on a brand-new "Williamson-Willey Pontiac Plaza" dealership at the corner of 35th Street and 6th Avenue South. The dealership occupied the entire block between 35th and 36th Streets and 5th and 6th Avenues. The 33,000 square-foot modern-style building was constructed by the Brice Building Company.
Williamson left the partnership before 1964.
