Cadillac Deville Models & History 1968

DEVILLE (V-8) – SERIES 683

On paper, it seemed that the main distinctions of cars in the DeVille lineup were the installation of a power-operated front seat with horizontal adjustment and the addition of illuminated door panel reflectors. There were, however, richer appointments inside and out, including the traditional rear fender Tiffany-like scripts and plusher upholstery trims. In addition, twice as many body styles were provided in DeVille level finish.
