1976 Cadillac Deville problems
The Cadillac DeVille is a model name used by Cadillac over eight generations, originally used to designate a trim level of the 1949 Cadillac Series 62 and later to designate a standalone model in the brand range. The last model marketed specifically as a DeVille was the 2005 full-size sedan, at the time, Cadillac's largest model.
For 2006, the Deville nameplate was retired, when the model line was carried forward (with minor revisions) as the Cadillac DTS, using a nomenclature adopted by the Cadillac STS and CTS.
Early history
The name "DeVille" is derived from the French de la ville or de ville meaning "of the town". In French coach building parlance, a coupé de ville, from the French couper (to cut) i.e. shorten or reduce, was a short four-wheeled closed carriage with an inside seat for two and an outside seat for the driver and this smaller vehicle was intended for use in the town or city (de ville). An (unshortened) limousine or (in the United States) town car has a division between the passenger and driver compartments and if the driver's seat is outside it may be called a sedanca de ville or town car.
The first Cadillac "Coupe de Ville" was shown during the 1949 Motorama. 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. The interior was black and trimmed in gray leather, including the headliner, to match the roof color. 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. The prototype "Coupe de Ville" was used by GM President Charles E. Wilson until 1957 when he presented it to his secretary. At some time during this period it acquired a dark Vicodec roof. The prototype "Coupe de Ville" was found and restored in the 2010s; it was in a private collection in London, Ontario, Canada as of 2017.
The Cadillac Series 62 Coupe de Ville was introduced late in the 1949 model year. Along with the Buick Roadmaster Riviera, and the Oldsmobile 98 Holiday, it was among the first pillarless hardtop coupes ever produced. At US$3,496 ($44,768 in 2023 dollars ) it was only a dollar less than the Series 62 convertible, and like the convertible, it came with power windows standard. It was luxuriously trimmed, with leather upholstery and chrome 'bows' in the headliner to simulate the ribs of a convertible top. In its first year the Series 62 Coupe de Ville only sold 2,150 units. But 1950 sales more than doubled to 4507, and in 1951 sales more than doubled again to 10,241 exceeding the sales for the Series 62 Club Coupe that year. Also, in 1951, Coupe de Ville chrome script appeared on the rear roof pillar for the first time, to further distinguish it from the Series 62 Club Coupe.
In 1956 the Series 62 Coupe de Ville was joined by the Series 62 Sedan de Ville, Cadillac's first standard production 4-door hardtop. Similarly to the Coupe de Ville, it was also more expensive and more luxuriously trimmed than the standard 4-door Series 62. With 41,732 sold, it also easily outsold the Series 62 sedan in its very first year. Given their sales success, it was only natural that the Coupe de Ville and Sedan de Ville were moved to their own separate series in 1959, the Series 6300, being joined by a DeVille convertible in 1964.
