The Cadillac DeVille was originally a trim level and later a separate model produced by Cadillac. The first car to bear the name was the 1949 Coupe DeVille, a prestige trim level of the Series 62 luxury coupe. The last model to be formally known as a DeVille was the 2005 Cadillac DeVille, a full-size sedan, the largest car in the Cadillac model range at the time.
Cadillacs of this period are increasingly popular with enthusiasts!
