Superior Coach Company (1940-1980) In 1940 the company changed its name again, to Superior Coach Company. School bus bodies were built primarily on Chevrolet/GMC, Dodge, Ford, and International Harvester truck chassis. In 1951 the Lima facility was expanded and a new facility in Kosciusko, Mississippi was opened. Sheller-Globe Corporation In 1969 Superior was acquired by the Sheller-Globe Corporation, an industrial conglomerate and auto parts maker based in Toledo, Ohio. The 1977 model year saw a major downsizing in the Cadillac automobile chassis used for the professional car business. In addition to being smaller, Cadillac's commercial chassis was significantly more expensive. Superior and other ambulance and funeral car manufacturers had to design new bodies and retool their factories, resulting in much higher consumer costs. The ambulance sector switched to larger van-based vehicles or and truck chassis. 1977 also brought new Federal Motor Vehicle Safety Standards for school buses built after 1 April, which increased both costs and engineering challenges. At the same time, a downturn in North American school bus purchase volumes began as the children of the Baby Boom generation completed their elementary and secondary educations. By 1980, Superior was one of the six major school bus body manufacturing companies in the United States, competing with Blue Bird, Carpenter, Thomas, Ward, and Wayne, as well as Gillig and Crown whose buses were primarily sold on the West Coast. Bidding competition for reduced volumes became devastating to profits and even liquidity; in 1979, Ward declared bankruptcy, reorganizing as AmTran the following year, which later became IC Bus. Faced with these challenges, school bus industry overcapacity, the loss of ambulance business in the professional car sector, and decreased sales of funeral coaches due to higher production and sales costs, Sheller-Globe liquidated its Superior Coach-related investments in late 1980, and portions of its assets were sold. Post-liquidation After Sheller-Globe announced the closure of its Lima bus and professional car manufacturing operations in 1980, several small businesses purchased portions of the assets, and carried on successfully with several product lines. School buses Although large school bus manufacturing was discontinued with the 1980 model year, Mid Bus—a new small business based in Lima organized by three former employees—resumed production of the smallest Superior school buses, beginning with a workforce of seven people. The business grew successfully, and after a move to a much larger facility at Bluffton, Ohio, it was acquired by Collins Industries in
