The Studebaker Wagonaire was a station wagon produced by the Studebaker Corporation of South Bend, Indiana, from 1963–1966. It featured a retractable sliding rear roof section that allowed the vehicle to carry items that would otherwise be too tall for a conventional station wagon of the era.
The Studebaker Wagonaire was based on the standard Lark station wagon body that was modified above the beltline. The roof was designed with a panel over the cargo bay that manually retracted into and then locked into position in the forward section of the roof above the rear passenger's seat. This configuration allowed Studebaker to boast that the Wagonaire could transport items (such as standard size refrigerators) in an upright position.
Early buyers soon found that their new wagons' roofs leaked water near the front of the sliding section. This problem was addressed – with limited success – by the factory. While the early roof seals were redesigned and improved, it was also critical that the drainage tubes in the roof slider assembly be kept clear, a factor that early owners were probably not aware of. A series of service letters were sent to dealers to address this but early negative reports probably tarnished what was otherwise a very sound 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$100.00 less than the sliding-roof wagons, but it was technically a "delete option", meaning that if the buyer wanted the fixed roof versus the slider, it had to be specifically ordered that way by the selling dealer and was not a separate model.
