A discussion of the Biscayne can be found here. Like many other GM 1950s dream cars (what they were popularly called at the time), the Biscayne was to have been destroyed. But by a quirk of fate it was not, and is now part of the Bortz collection of concept cars. Some background on this can be found here and here.
The Biscayne is interesting because its size. It was designed at a time when American sedans were becoming wider and longer. I couldn't find size statistics, but estimating from photos, my best guess is that the Biscayne's wheelbase was about 108 inches (2,743 mm), in the range of "compact" cars introduced by GM, Ford and Chrysler for the 1960 model year or early 2000s Ford Mondeos.
The nicest feature in my opinion is the treatment of the passenger greenhouse. It's light and airy while the roof's side curves and the C-pillars add the right touch of solidity. The interaction of the aft side windows, the backlight (back window) and C-pillars works very well. The side sculpting that extends around to the rear is also well handled. In contrast, the front end has a number of odd features.
The five images below seem to have been taken at the same photo shoot because the same house is in the background. Colors vary due to aging of the original photos. I adjusted these internet-based images as best my iMac would allow.
