This is a pic of Cotton Dunn's (played by actor John Byner) 1960 Lincoln Continental Convertible. When originally watching this show I always thought his Lincoln was probably a '58...but later when actually comparing grills and slight changes between the 1958-1960 models--I'm almost positive this this a '60. This should have at least 3 stars as it was shown frequently and was this character's main car. This picture is from 3rd season episode 7 ("Love Never Dies").
