The automobile used by George and Marion Kerby, before they become ghosts, and later by Cosmo Topper – whose own car is a 1936 Lincoln Model K – is a custom-made vehicle with a resemblance to Cord and Duesenberg automobiles of the 1930s. Production models of a Cord were too small to use, so the custom body was built on the chassis of a 1936 Buick Roadmaster by Bohman & Schwartz and the external exhaust pipes characteristic of a supercharged Cord are non-functional; the Buick Roadmaster of the time used an eight-in-line ("straight eight") engine whereas the Cord used a V-8 engine- so external exhaust pipes on both sides of the hood (as per the Cord arrangement) would have meant that at least one side of the car (and probably both) used dummy external pipes. The Buick trunk had special compartments for camera equipment. Afterwards, the car was purchased by the Gilmore Oil Co., who used it for many years for promotional purposes. In 1954, the vehicle was updated utilizing a Chrysler Imperial chassis and drive train.
