In 1970, a facelift included a grille with 13 vertical blades set against a delicately cross-hatched rectangular opening. The bright metal headlamp surrounds were bordered with body color to give it a more refined look.
Exterior distinctions came from a DeVille script above the rear end of the belt molding and from the use of long rectangular back up light lenses set into the lower bumper as opposed to the smaller square lens used on the Calais. A new feature was a body color border around the edge of the vinyl top covering, when this option was ordered.
The 1970 model year was both the last year that DeVille offered a convertible body style and for pillared sedans until hardtops were permanently dropped in 1977.
