The Mills Companies began in 1922, when Stewart C. Mills, Sr. purchased the Lively Auto Company and began selling Chevrolets and Hupmobiles in Brainerd, MN.

The Mills Auto Group now has five automotive dealerships, 3 in Brainerd, and 2 in Willmar, MN, a state-of-the-art collision center / auto body shop in Brainerd, and a Wholesale Parts Supply business based in Willmar serving the state of Minnesota, areas of North Dakota, South Dakota and Wisconsin.

Our Company history reinforces the importance of the cornerstone foundations of our business and success, which are: Honesty, Integrity, Efficiency, Hard Work, Courtesy, Customer Service and Loyalty. They are our trademarks and our team's way of doing business.


The building and property which now house Mills GM was originally the Mills Ford dealership when they moved from their downtown location in June, 1986. A decade later, the Mills family purchased the GM franchises from the Imgrund family and began the conversion from a Ford store (which is now located 1 mile north) to a General Motors store. In December, 1996, Mills GM opened in its current location.
