1987 Porsche 928 S4 Factory Custom 4-Door Sedan

The 928 joined the 924 as the first Porsche with a front-mounted, water-cooled engine, in this case, a 5.4-liter V8 unit producing 326 horsepower. The transmission is placed in the rear to balance the weight, and a Weissach rear axle was used with a new suspension system to ensure excellent roadholding. In 1986, Porsche and AMG built this prototype. A custom 928 four-door sedan, this rare and unusual car was delivered to Heinz Prechter, founder and CEO of ASC (American Sunroof Corporation), whose large automotive aftermarket firm was headquartered just south of Detroit, and which enjoyed a close relationship with the Porsche factory. The workmanship of this conversion is impeccable, being equal or better than the legendary fit and finish of a new Porsche. The interior is lined in sumptuous burgundy leather matching the exterior paintwork.
