Porsche 928 S

The Porsche 928 S debuted in 1980 as a more powerful and visually aggressive version of Porsche's V8-powered grand tourer. For North America, the 'S' arrived in 1983 with a 4.7-liter V8, offering a significant performance jump over the original 4.5-liter car. Instantly recognizable by its new front and rear spoilers, the 928 S solidified the model's identity as a comfortable, high-speed, long-distance cruiser.

Collectors appreciate the 928 S for its unique design and its status as Porsche's flagship model of the era. The car's advanced engineering, including the passive rear-steering Weissach Axle, and luxurious interior set it apart from the more spartan 911. Manual transmission examples are particularly sought after by enthusiasts, as most 928s were equipped with automatic transmissions better suited for grand touring.

The market for the 928 S has been climbing steadily after years of being undervalued. With an average sale price around $22,820, well-sorted drivers are still accessible. However, project cars can be found for very little, while exceptional, low-mileage examples have sold for over $140,000. Buyers are increasingly recognizing the 928 S as a great value in the classic Porsche world, but neglected cars can be incredibly expensive to sort out.

Prices range from $1,850 for project cars to $142,069 for pristine, top-spec examples.
