Coupe DeVille, a name that had been around for over two decades, was advertised as “America’s favorite luxury car.”
The mid-1970s edition had a vinyl cabriolet roof with chrome accent strip at the leading edge, and a squarish quarter window (considerably larger than most such windows at this time).
Sedan DeVille continued the pillarless hardtop that had been part of the GM tradition for years, but would soon be doomed to extinction.
Sedans also featured narrow sail-shaped fixed windows in the roof quarter panels.
DeVille’s crosshatch grille was dominated by a framed set of vertical bars, peaking forward slightly at the center.
An upper horizontal bar above the grille mesh held a Cadillac script at the side and swept down alongside the grille, then outward to wrap around the fenders just above the bumpers.
Quad rectangular headlamps met wraparound cornering lamps.
Set into traditional tall housings at rear fender tips were vertical inward-facing and outward-facing side lamps.
Horizontal taillamps were below the deck lid; backup lamps in toward the license plate housing.
Script nameplates were on rear quarter panels, just above the bodyside molding.
New Magnan ribbed knit upholstery came in six colors; Merlin Plaid or Manhattan velour each in two. Eleven leather combinations were available. Distinctive simulated-rosewood appliques and laminates highlighted doors and dash. 50/50 seats had individual fold-down center armrests. The standard 500 cu. in. V-8 (whose days were numbered) could have either a four-barrel carburetor or fuel injection.
The special-edition Coupe DeVille d’Elegance now carried standard opera lamps behind the quarter windows, which were optional on other DeVille coupes.
D’Elegance hoods omitted the customary “V” and crest, substituting a distinctive stand-up see-through ornament along the chrome windsplit.
Styling highlights included dual accent stripes on front and sides of hood, door surfaces, and rear deck (in choice of eight colors).
Interiors contained new loose-pillow style 50/50 seats in two-toned Magnan ribbed knit cloth (four colors).
A “DeVille d’Elegance” script was on the instrument panel and sail panels (coupe only).
The package also included wide brushed-chrome lower door moldings, and bodyside moldings with colored vinyl inserts to match the vinyl roof color.
Coupe DeVille’s Cabriolet roof option, with Elk Grain vinyl padded vinyl top, added for 1976 a decorative Cadillac crest on the sail panels.
Also part of the package: a standup see-through hood ornament, chrome roof moldings, and French seam around the backlight.
Cabriolet roofs had been available on Coupe DeVille since 1974.
