  • Bob Ryan Jr.
    Dealer Principal
    763 682 2424

    In 1955, my father, Robert Ryan Sr. opened his own used vehicle agency in Sioux Falls, South Dakota, operating as Mid Town Motors. In 1965 he was awarded the Rambler and Mercedes Benz franchises and ultimately was able to obtain the Chrysler & Plymouth franchises. 

    In 1966, my dad opened Ryan Motors in Sioux Falls, South Dakota operating as Ryan Motors Chrysler Plymouth. He was awarded Chrysler's "Pacemakers Top 100 Club Award" from Chrysler for multiple years.

    In 1971, the Ryan family moved to Texas after selling their automobile interests to Henry and David Billion. David and his son are still in business today.

    We then moved to Houston and operated Midtown Chrysler Plymouth for one year until Katy Road Chrysler Plymouth, Chrysler's flagship facility opened. 

    In 1975, the Ryan family sold out to the Benson family and returned to the Midwest, where most of the 14 children, 22 grandchildren and four great grandchildren reside today.

    Fifty years later, the Ryan family proudly opened another Chrysler flagship designed facility, for the franchises of Chrysler, Dodge, Jeep and Ram truck in Buffalo, MN and then soon after, another CDJR dealership in Monticello, MN. 

    I would like to personally thank our customers for sharing their experiences with our company at DealerRater, Google and Cars.com, where we are proud to say that we have over 10,000 public reviews.
