American Specialty Cars (commonly known as ASC or American Sunroof Company) was an automobile supplier of highly engineered and designed roof systems, body systems and other specialty-vehicle systems for the world’s automakers. The company was headquartered in Warren, Michigan, in the United States and was one of several coach convertible builders. ASC sold assets to its Creative Services division in late 2016 to Roush Industries. In late June 2017, ASC effectively ceased operations, laying off all staff and had tooling and production equipment removed from the manufacturing plant in Lexington, Kentucky.
Founding
The company was founded by Heinz Prechter in Los Angeles, California as the American Sunroof Company in 1965. In 2004, the aftermarket sunroof business was sold to Inalfa, and the company changed its name from American Sunroof Company to American Specialty Cars, with a "new emphasis on handling design, engineering and manufacturing of low-volume niche vehicles".
All employees were terminated June 27, 2017 and ASC ceased operations. Major manufacturing operations were sourced to other suppliers, mainly Toyota and FCA, effectively shutting down production operations.
