These courtesy cars and SUVs are hand-picked from our new BMW, Mercedes-Benz and Cadillac inventory. They are gently driven for a short period of time and fully cared for and maintained by our service team, and then made available for sale. Retired courtesy cars and SUVs from Luxury Auto Mall of Sioux Falls offer an excellent opportunity to drive a new BMW, Mercedes-Benz or Cadillac at a lower price and still receive the full benefits of new vehicle rebates, incentives and offers.
