Deville Cadillac Models & History 1966

the general styling theme found on Calais models, the DeVille series was again distinguished with Tiffany-like scripts above the rear tip of the horizontal body rub moldings. Standard equipment additions followed the pattern of previous years. Cadillac crests and V-shaped moldings, front and rear, were identifiers.
