Wilhelm’s opened its Bismarck dealership in 1986, and closed in 2007 as a result of a GM reorganization. Schwan GM Auto Center assumed franchise rights to the Buick and Cadillac names. Wilhelm’s still operates its dealership in Jamestown, North Dakota.
The adjacent building located directly east was home to Fleck Motors for several decades.
Today, the site is home to Broadway Centre, a mixed-use facility.
