What automobile company made the 'de Ville' series of cars?

The Cadillac de Ville was one of the longest-running car marques in the history of General Motors. The first de Villes rolled off of the production line in 1958. Production continued up to 2005, spanning 8 generations.

The name comes from the French phrase 'de la ville' which means “of the town. The Cadillac Coupe de Ville was designed to be a luxury town car. The first concept and prototype model, called the 'Coupe de Ville', was shown at the 1949 Motorama show. The key standout features included the Cadillac Sixty Special chassis, dummy air scoop, chrome trim, a one-piece windshield, and black with gray trim interior. It was even equipped with power windows and a telephone.

Along with other General Motors cars like the Chevrolet Bel Air, the Cadillac Coupe de Ville, in its earliest generations, was built as a declaration of an entirely new outlook on automobile design. Gone were the warring days of pure function and efficiency of the 1940s and early 1950s. It was now time for style and decadence,which included huge tailfins.

The eight-generation DeVille, they changed the spelling, was the final one produced, running from model years 2000 to 2005. The DeVille name was retired in 2006 and replaced with the DTS line, which is seen as the continued development of the DeVille model line.
