S.D. Codified Laws § 32-6B-87
A vehicle dealer licensed in this state may lease space in the common area of a shopping mall for the display of new vehicles without a supplemental license if the shopping mall is located within the corporate limits of the municipality where the dealer maintains its principal place of business. A dealer may not display more than four vehicles in a single shopping mall, contract for an exclusive right to lease all common areas of the shopping mall available for vehicle display, or negotiate the sale of any vehicle on the premises of the shopping mall. The lease shall be in writing. The dealer shall maintain a copy of the lease for a period of one year from the date of expiration of the lease and allow a representative of the department to examine the lease at the dealer's principle place of business during regular business hours. For purposes of this section, a shopping mall is any building or series of interconnected buildings containing a minimum of two hundred thousand square feet of leasable space for occupancy by a variety of retail stores and restaurants which is located in a municipality with a population that exceeds thirteen thousand. The provisions of this section do not apply to a licensed dealer with a principal place of business located on the premises of the shopping mall.
