The 1970 DeVille received a facelift that included a grille with 13 vertical blades set against a delicately cross hatched rectangular opening. The bright metal headlamp surrounds were met with more body color paint for a more refined look. Narrow vertical “vee” taillights were seen again.
1970 would be the last year the DeVille ever offered the convertible body style.
DeVille accounted for 76% of Cadillac sales in 1970. Never again would Cadillac sales be dominated to such a degree by a single model.
