Deville Cadillac History 1971

Deville Cadillac Models & History 1971

To distinguish the Calais from the DeVille visually, DeVilles had thin, bright metal rocker panel strips and signature scripts on front fenders bearing the series name. The bottoms of the rear fenders were decorated with a bright metal beauty panel that was wider than the rocker strips, and blended into the molding running along the bottom of the fender skirt. As on Calais, the lower beltline molding ended on the elliptical rear fender bulge, where thin rectangular side markers were placed above and below the chrome strip. Only two body styles remained in this series.

  • dual rear cigarette lighters
  • Two-Way horizontal control front seat adjusters
  • rear center arm rest in all models except convertibles.
