If the applicant sets up a principal place of business in more than one county of this state, the applicant shall secure a separate license for each county. However, a vehicle dealer or used vehicle dealer who sells or displays a vehicle that is twenty model years or older or an emergency vehicle dealer is not required to secure a separate license for each county if the licensee has otherwise complied with this chapter, has notified the department of the display, and the display does not exceed fifteen consecutive days. No license for any additional county may be issued until the department is furnished with proof that the applicant has a principal place of business in the county and has otherwise complied with this chapter.
