Overview of 1988 Porsche 928 S4 For Sale by Owner

Originally conceived as the successor to the 911, the Porsche 928 ultimately carved out its own place in automotive history as one of the finest grand touring cars ever built. By the time the S4 debuted for the 1987 model year, Porsche had significantly refined the platform with more power, improved aerodynamics, and updated styling, transforming it into a true high-speed GT capable of crossing continents in comfort. Showing 128,094 miles, this 1988 Porsche 928 S4 is finished in elegant Slate Grey Metallic over a Gray leather interior. Featuring a power sunroof, forged alloy wheels, an aftermarket exhaust, and Porsche’s renowned front-engine V8 layout, this S4 represents one of the most sophisticated and underrated performance cars of its era.

Exterior and Interior

The exterior of this 1988 Porsche 928 S4 is finished in timeless Slate Grey Metallic, a sophisticated color that complements the car’s smooth, aerodynamic bodywork. The S4 introduced redesigned front and rear fascias that significantly improved both appearance and high-speed stability while preserving the unmistakable silhouette that made the 928 instantly recognizable. A factory rear spoiler enhances both styling and aerodynamic performance, while lightweight forged alloy wheels reduce unsprung weight and complete the car’s purposeful stance. Even decades after its introduction, the 928’s blend of elegant curves and advanced engineering remains one of Porsche’s most distinctive designs. The interior of this 1988 Porsche 928 S4 showcases Porsche’s dedication to creating a luxurious grand touring environment without sacrificing driver engagement. Gray leather power-adjustable front seats provide exceptional comfort and support for long-distance driving, while automatic climate control ensures year-round comfort regardless of conditions. The driver-focused cockpit places all major controls within easy reach, emphasizing the 928’s mission as a high-speed touring machine rather than a stripped-down sports car. An aftermarket audio head unit adds modern connectivity and functionality, while the power sunroof further enhances the cabin experience, allowing occupants to enjoy open-air motoring while maintaining the refinement expected of Porsche’s flagship GT.

Engine

Powering this 1988 Porsche 928 S4 is a 5.0-liter naturally aspirated V8 equipped with Bosch LH-Jetronic electronic fuel injection, an advanced engine management system that helped make the S4 one of the most technologically sophisticated performance cars of its day. Factory rated at 316 horsepower and 317 lb-ft of torque, the all-aluminum V8 delivers effortless acceleration with a broad, linear powerband ideally suited for grand touring. Power is sent to the rear wheels through a smooth 4-speed automatic transmission, while Porsche’s near-perfect weight distribution, achieved through its rear-mounted transaxle, provides exceptional balance and stability at speed. An aftermarket exhaust adds an even more pronounced V8 soundtrack, allowing the engine’s distinctive character to shine while reinforcing why the 928 S4 continues to be celebrated as one of Porsche’s greatest front-engine performance cars.

With just 1,025 miles showing, this 1990 Chevrolet Corvette ZR-1 is an extraordinary low-mileage example of one of the most important American performance cars of its era.
