1990 Porsche 928 S4 5-Speed

Description

Produced from 1978 through 1995, the Porsche 928 was the company's intended successor to the 911 — a front-engined, water-cooled grand tourer powered by a V8 that Porsche believed represented the future of the brand. History proved otherwise, but the 928 S4, introduced for 1987 with a revised 5.0-liter V8 producing 316 horsepower and a restyled body, stands today as the most refined and arguably most desirable iteration of the model.

This example is finished in Grand Prix White over a Black leather interior. While it was built with an automatic transmission, it has since been fitted with a 5-speed manual transmission reportedly installed by Carl Faust of 928 Motorsports in Neenah, Wisconsin.

Following the seller’s acquisition in late 2023, this 928 S4 received a timing belt service, fuel system service, and Pirelli tires mounted.

This 1990 Porsche 928 S4 is now offered with a clean CARFAX Vehicle History Report and a clean Colorado title in the seller's name.
