This almost-a-convertible-not-quite-an-El-Camino wagon was created by Studebaker on the Lark station wagon body. The retractable roof was built into the rear to allow tall cargo to be transported upright. From the ad above, I assume this meant your fishing poles, or your daughter, but I’m sure there were other ways to get them into a converntional wagon.

Any owner of a 240 with a sunroof can guess what problems arose from the Wagonaire’s retractable roof; it leaked like a sieve. Although Studebaker fixed this problem in later years, the model was doomed to a production run of 3 years and open air rear styling for wagons never caught on.
