This line reflected Series 62 styling revisions, but incorporated a DeVille signature script above the lower
beltline molding, near the rear of the body. Standard features on DeVilles (and on base 6200 convertibles) were
the same as on closed body 6200 models, plus two-way power seats and power windows. Model 6367E, the
Eldorado Biarritz convertible, had special styling with untrimmed body sides, full-length stainless steel
underscores and a rectangular grid pattern rear decorative grille. Power vent windows, white sidewall tires and
six-way power seats (in bench seat mode) were standard in Eldorados.

dropped from the 62 Series.
