purchased Meteor Motor Car Company in Piqua, Ohio in 1954. Meteor built professional cars, such as limousines and ambulances. In 1956, Wayne acquired A.J. Miller's professional car building company of Bellefontaine, Ohio. The A.J. Miller Company had begun in 1853 by making horse carriages and then started making automobiles in the early part of the 20th century. However, the small company found it could not compete in the general market with the larger automobile makers, so they began specializing in hearses and ambulances. Over the years the Miller hearses became known and used throughout the world. The Miller Co. was combined with Wayne's existing professional car subsidiary, Meteor Motor Car Company, forming the new Miller-Meteor (M-M) division of Wayne. Professional car manufacturers Miller and Meteor, newly combined as Miller-Meteor, were brought into the fold of Divco-Wayne as the newly formed conglomerate was developing its opportunities in this field. Although the recently combined Miller-Meteor company was initially based at Bellefontaine, Ohio, originally the home of the A.J. Miller Company, under Divco-Wayne ownership, it was later relocated to Piqua, Ohio, Meteor's old hometown nearby. Ecto-1, the vehicle used by the protagonists in the 1984 film Ghostbusters and its 1989 and 2021 sequels, is a 1959 Cadillac fitted with a Miller-Meteor ambulance body. Cotner-Bevington Divco-Wayne acquired Cotner-Bevington Coach Company (C-B) in 1965, making it a subsidiary of Wayne Corporation. Founded as Comet Coach Company, the coachbuilder sold the rights in 1959 to the "Comet" name" to Ford Motor Company (which sought to use it for the Lincoln-Mercury Division); in 1960, the Mercury Comet was introduced. In response, Comet Coach renamed itself Cotner-Bevington Coach Company, taking on the names of its two founders; the company also relocated from Memphis, Tennessee, a few miles north to Blytheville, Arkansas. At the time of its acquisition by Divco-Wayne, Cotner-Bevington specialized primarily in ambulances based on Oldsmobile commercial chassis. In 1968, Wayne began production of truck-based ambulances, using the Cotner-Bevington facilities. For 1968, the "Sentinel" (based on the Chevrolet Suburban) was introduced, expanding to the "Vanguard" (based on the Chevrolet Van) in 1971, and "Medicruiser" (based on Dodge Ram Van) in 1973. The Sentinel received a headroom increase for 1971, but were only built through the 1972 model year. After that, the Sentinel brand name was used on Wayne's line of Type I (pickup chassis) modular ambulances. Body shells were produced at the Richmond, Indiana, bus plant for
