DeVilles had all equipment standard on Calais models, plus
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.
