Two prototypes were made for 1962, each with a unique body. One a convertible and the other a hardtop. The prototypes came directly from Buick Engineering, both had been given two 4-barrel carburetors by the engineers thus increasing the prototype's horsepower a little more than 80 hp. They had features from the '61, '62, and the '63 production models. Some features, such as the two 4-barrel carburetors, were left out of the production-line Skylarks. The prototypes were also were longer, and wider than the production models. Of the two prototypes, only the hardtop still exists and resides with its owner in Michigan. It is possible the convertible prototype still exists in the Sloan Museum collection.
