OK Used Cars 1925 Phone Case

Used car lots have always had some reputational issues to deal with, even back in the early days of the automobile. While certified used cars are quite common today, the 'OK Used Cars' program was Detroit's attempt at combatting negative opinions about buying a used car by creating the first certification program. 'OK Used Cars' had completed a series of tests before being certified, including a thorough inspection, complete servicing, and several points of reconditioning. The certified vehicles would be added to the lot with a warranty included, something that was previously unheard of with a used car. The program was a success, and would grow and evolve, but by the '50s, the 'OK Used Cars' sign could be found at car lots in everywhere.
