Official Code of GA Annotated, O.C.G.A 43-47-2 (3), states that a dealer must maintain an “established place of business” and defines one as “a salesroom or sales office in a building or on an open lot of a retail used car dealership or at which a permanent business of bartering, trading, offering, displaying, selling, buying, dismantling, or rebuilding wrecked or used motor vehicles or parts is carried on, or the place at which the books, records, and files necessary to conduct such business are kept. Each such place of business shall be furnished with a working telephone listed in the name of the licensee for use in conducting the business and shall be marked by an appropriate permanent sign as prescribed by the appropriate division under this chapter.”
