The 1959 Cadillac has always been memorable with its classic tailfins with dual taillights. In 1959 the de Ville models became series 6300, all Cadillac’s of this year shared the same 130-inch wheelbase with a 390 cu in engine with 325 horsepower for sheer power. They also brought a touch of class with script nameplates on the rear fenders, and it was the first year for those iconic fins.
