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. The dealership franchises include: Ford, Lincoln, GMC, Buick, Honda, Chrysler, Dodge, Ram, Jeep, Nissan, and Toyota.

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.

Mills Auto Center is just what the name implies, a Willmar shopping center for three franchises under one roof. 

The roots of this dealership date back to the 1960's and in 1996, Stewart C Mills, Jr. and Henry C. Mills ll purchased what is now called Mills Auto Center.

Since 1922, Mills has built a family tradition of honesty, trust and integrity. We strive to develop mutual, long-term relationships with our customers through dedicated team members creating world class experiences. It is our sincere goal to ensure that all of our guests' and customers' expectations are exceeded.
