Ford contracted Intermeccanica Custom Coach Builders to build the Mustang Cabrio convertible. The conversion used parts from a Mercedes-Benz.
In 1980 this project started out as a deal with FORD to produce factory-authorized Mustang convertibles. They had beaten Carson Concepts and ASC(American Sunroof ) for the contract since IM had the best mechanism developed. The mechanism was like a Mercedes 220, finished with boot and folded down to a 4 ½” stack under the cover. Ford later pulled the plug on the deal for one reason or another.
The ASC McLaren is a direct descendant of the Intermeccanica Mustang convertible. Approximately 1200 non-factory authorized Mustang convertibles were produced.
