to address this but early negative reports probably tarnished the design. As a result of the leak problem, fixed-roof station wagons were rushed into production alongside the Wagonaire and became available in January 1963. These sold for US$100 less than the sliding-roof wagons, but it was technically a "delete option" and not a separate model. When Studebaker closed its South Bend, Indiana, assembly plant and continued production at its Hamilton, Ontario, Canada, plant, the company discontinued the Avanti and Hawk, but continued to build Lark-based sedans and Wagonaires. The 1964 models, which were built only in Canada after December 1963, were the last to carry Studebaker's own engines. Beginning with the 1965 models, General Motors supplied engines based on the Chevrolet six-cylinder and V8 designs. The 1965 models were available only with the sliding roof. The fixed-roof option made a return for Studebaker's final model year in 1966, but the third seat was no longer offered. In addition, the 1966 Wagonaire finally was made a model in its own right, blending the exterior features of the Commander with the interior trim grade of the sporty Daytona. There were also fixed-top Wagonaires available in 1966; while a total of 618 of all types of Wagonaires were built for 1966. Daytona version The 1963–64 Daytona version of the Wagonaire could be equipped with a V8, Carter 4-barrel carburetor, and a column mounted shifter manual transmission with overdrive. Bucket front seats along with a center console-mounted automatic transmission selector were available. The Wagonaire could also be ordered with any of Studebaker's available "R-series" high-performance Avanti V8 engines and the four-speed floor-shift manual transmission. Scale models Matchbox-Lesney made a miniature Wagonaire that included a sliding roof section. The scale model was available for many years after Studebaker stopped production of the actual vehicle. Husky Toys also manufactured a model Wagonaire that was similar in size to the Matchbox product and also featured the sliding rear roof panel. Revival of the concept The concept of the retractable roof was picked up by General Motors for a model in its GMC Envoy line in 2003 as a 2004 model. Advertisements for the new Envoy XUV incorrectly touted the feature as "first-ever." An additional feature adopted by GMC was the power operation of the roof section and a movable partition between the passenger area and cargo space. The Envoy XUV model was discontinued in 2005.
