For 1978, Cadillac's commercial chassis production further declined to only 852 units; Miller-Meteor received orders for only 4 ambulances. There were no 1979 Miller-Meteor ambulances. On December 13, 1979, the company, with roots tracing back to 1853, closed its doors. The company laid-off 252 employees and terminated the contracts of their 34 North American distributors. By the late 1970s, as the situation became critical, Wayne Corporation, the parent of M-M and C-B, and Wayne's Thyssen owners chose not to invest heavily in either firm as would have been required in the uncertain futures of the diverging professional car and ambulance building industries. There were no buyers for either subsidiary as a going business. In 1980, Cotner-Bevington ambulance product line was sold to Gene Knisley, owner of Mid-Continent Conversion Co., which was an ambulance and medicar builder in Kansas City, Missouri. The C-B plant in Blytheville, Arkansas was closed.
