Thanks for sharing this wonderful car with the people out here on the net. There is something special about the Cadillacs. I love most all of them. Most people do not know how Caddy started. Henry Ford's failed business back in the early 1900's taken over by creditors and renamed Cadillac. WHO would have ever thought that one up. You have a beautiful car. It must feel awesome to drive down the road in that car. Have fun! Thanks again for showing your ride. regards, Den
