Hmmm. I'd love to see this car in person. Seems to be in very nice condition. The fin mystery is intriguing. Here's a link to the rear of a '61 at about the same angle as the one in on the website: http://www.imperialclub.com/Yr/1961/SpottersGuide/Imp-rear.jpg Compare that with the one on e-bay: http://i24.ebayimg.com/01/i/02/0f/9b/f0_12_s.JPG Sure seems like the fins are not as high. Anyone near San Leandro, Ca that can solve this mystery?
