Deville Cadillac Models & History 1974

DeVilles again had all Calais equipment plus

  • rocker moldings
  • rear center arm rests
  • rear cigar lighters
  • power front seat adjuster

A DeVille script nameplate replaced the Calais signature above the rear tip of the lower belt molding. New options included a DeVille d’Elegance luxury appointments package and a fully padded vinyl Cabriolet roof treatment. Ingredients of the former package were

  • velour upholstery
  • DeLuxe padded doors
  • front seat back storage pockets
  • deep-pile carpeting
  • floor mats
  • see-through standup hood ornament
  • vinyl tape accent stripes

The Cabriolet group incorporated a landau style top with bright metal forward divider strip. A Space Saver spare tire was standard when DeVilles were ordered with optional white sidewall steel belted radial tires.
