The Alfa Romeo Spider Series 4 (S4) represents the final and most refined version of a design that debuted in 1966. Launched for the 1991 model year, the S4 featured a major redesign by Pininfarina that smoothed the bodywork, integrated body-color bumpers, and added a new tail with full-width taillights. Under the hood, the 2.0L twin-cam four-cylinder engine received Bosch Motronic electronic fuel injection, which improved reliability and drivability over the previous SPICA systems.
Collectors are drawn to the S4 for its blend of classic style and modern convenience. It's the easiest of the classic Spiders to live with, thanks to standard features like power steering, an improved driving position, and often, factory air conditioning. The Motronic injection makes it a simple car to maintain for those familiar with 1990s systems, and parts availability is quite good. It offers the vintage open-top Italian experience without the fuss of older, more temperamental models.
The market for the S4 is mature and stable, with an average sale price around $17,000. It's an affordable classic, but exceptional, low-mileage examples, especially in desirable colors, can sell for significantly more. As the last of the rear-wheel-drive Spiders, its place in Alfa Romeo history is secure, ensuring continued interest from enthusiasts.
Buying Tips
- Check for rust thoroughly, especially in the floor pans, rocker panels, spare tire well, and around the jack points.
- The 2nd gear synchro is a known weak point; ensure it shifts smoothly without grinding when the gearbox is cold and warm.
- Test all electronics. The Bosch Motronic fuel injection is reliable, but aging wiring and sensors can cause erratic idle or poor running.
- Inspect the convertible top for tears, shrinking, and damaged seals, as a full replacement can be costly.
- Verify the condition of the rubber 'flex-disc' giubos, as worn ones cause driveline vibration.
Prices range from around $4,250 for projects to over $75,000 for concours-quality examples.
