In its heyday, Duesenberg made some of the most amazing luxury cars in the world. Chief among these was the Model J, but the Whittell Coupe is a cut above even this. This one-off was the result of a collaboration between designer Franklin Q. Hershey and the car's owner, Captain George Whittell Jr. It will be auctioned at Pebble Beach in August by Gooding & Co., who describe it as "America's most elegant automobile". A reasonable claim.
