1966 Cadillac DeVille Convertible – Rebuilt 429 V8, Mist Blue, Power Everything

This 1966 Cadillac DeVille Convertible was built at Cadillac’s Detroit, Michigan assembly plant and represents one of only 19,200 droptop DeVilles produced that year. Finished in Mist Blue (code 20) with an Ivory power-folding canvas top, straight and solid bodywork, and a recently rebuilt drivetrain backed by a binder of receipts, this is a well-cared-for DeVille that presents beautifully and drives as a proper Cadillac should.
