It was built on a Cadillac Sixty Special chassis and featured a dummy air-scoop, chrome trim around front wheel openings, and a one-piece windshield and rear glass.

It was equipped with a telephone in the glove compartment, a vanity case and a secretarial pad in the rear armrest, power windows and highly decorative chrome interior trim.

[4][5] The 1959 Cadillac is remembered for its huge sharp tailfins with dual bullet tail lights, two distinctive rooflines and roof pillar configurations, new jewel-like grille patterns and matching deck lid beauty panels.

A total of 143 options including bucket seats with wool, leather, or nylon upholstery fabrics and wood veneer facings on dash, doors, and seatbacks, set an all-time record for interior appointment choices.

In 1966, changes included a somewhat coarser mesh for the radiator grille insert, which was now divided by a thick, bright metal horizontal center bar housing rectangular parking lamps at the outer ends.

Cadillac "firsts" this season included variable ratio steering and optional front seats with carbon cloth heating pads built into the cushions and seatbacks.

Prominent styling features were given a powerful frontal appearance with forward-leaning front end, long, sculptured body lines, and redefined rear fenders that had more than just a hint of tail fins in them.

Coupe de Villes got a new roofline, inspired by the Florentine show car created for the 1964 New York World's Fair, that gave rear seat passengers added privacy.

New standard DeVille features included non-glare rear-view mirror, electric clock, Automatic Climate Controls, padded dashboard, Hazard Warning system, outboard seatbelt retractors and rear cigarette lighters in all styles.

On the inside enriched appointments included molded inner door panels with illuminated reflectors and a selection of 147 upholstery combinations, 76 in cloth, 67 in leather and four in vinyl.

Exterior distinctions came from a De Ville 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.

Horizontal beltline molding ran from behind the front wheel housing, almost to the rear, stopping where an elliptical bulge in the body came to a point and where thin rectangular side markers were placed above and below the chrome strip.

DeVilles were set apart visually by thin bright metal rocker panel steps and signature script on the front fenders bearing the series name.

One of the first production examples of what are now more commonly called airbags, this option provided protection for front seat occupants in the case of a frontal collision.

Similar to the Sixty Special Brougham's package of the same name, it featured velour upholstery, Deluxe padded doors, front seatback storage pockets, deep pile carpeting, floor mats, see-through standup hood ornament and vinyl tape accent stripes.

New standard equipment included front fender lamp monitors, power door locks, high energy ignition, steel-belted radial whitewall tires.

Cadillac also offered Track Master, a computerized skid prevention system that automatically pumped the back brakes in an emergency to shorten stopping distance.

[16] The floor bed could carry flat plywood 4-foot × 8-foot sheets with the tailgate closed, while the two-seat front cabin offered driver and passenger a plush ride.

Developed by the Eaton Corporation - with design elements that had been tested for over 500,000 miles (800,000 km) - allowed various engine computers to decide how many cylinders were needed to power the car for optimal fuel economy.

This new power plant featured a closed-loop digital fuel injection system, free-standing cast-iron cylinders within a cast-aluminum block, and was coupled with a 4-speed automatic-overdrive transmission.

The wide parking lamps below the quad headlamps now had clear frosted lenses (previous years they were amber), with satin gold-colored winged Cadillac emblems centered on each lens.

These little chrome corner pieces, mounted on the filler panels, were prone to pitting as they were made of a different material than the bright aluminum trunk trim and upper license late surround.

1987: 1987 saw a new front-end design including revised cornering lamps in front and one-piece composite headlamps flanked a trapezoid-shaped grille with a bold egg-crate texture.

Cadillac's main competition in this time frame continued to be Lincoln, which, alongside their successful Town Car, was now fielding an all-new front-wheel-drive Continental (based on the Ford Taurus).

New options included a driver's side airbag, Bose compact disc player, electrically-heated windshield, and full reversible carpeted floor mats.

[26] The Touring Sedan was offered in 5 monochromatic paint schemes: Carmine Red; Cotillion White; Black; Dark Slate Gray metallic; and Black Sapphire Metallic; and included larger 16 x 6.5-inch forged aluminum wheels with a wreath and crest center caps, P215/60R16 Goodyear GA all-season radial tires; quicker 17:1 steering ratio; and a model-specific deep tan interior — marketed as Beechwood, with leather seating areas and revised seat contouring with integral lumbar support; six-way power seats and recliners for driver and passenger; as well as genuine American Walnut wood accents on the doors and instrument panel.

1990-1993 Coupe de Ville production details: Declining popularity led to the discontinuation of GM's last full-size, six passenger two-door with the 1993 model year.

The Concours featured an adaptive, continuously variable road sensing suspension initially marketed as CVRSS and later as MagneRide, a first on the DeVille series.

The Deville DTS was newly available with stability control, continuously variable road sensing suspension (CVRSS) with magnetorheological dampers (marketed as MagneRide), and onboard navigation.

[35][36][37] Because the system outputs a standard NTSC composite video signal and the used parts are somewhat easy and inexpensive to find, it has become a popular choice for fitting thermal night vision to other vehicles.
