The Mercedes-Benz W116 was the first model series officially named the S-Class, setting a new standard for luxury sedans when it debuted in 1972. Known for its advanced safety features, including a padded interior and a reinforced passenger cell, it showcased the brand's commitment to engineering excellence. The lineup's crown jewel was the 450 SEL 6.9, which featured a massive 6.9-liter V8 and a sophisticated hydropneumatic self-leveling suspension, making it one of the fastest and most advanced sedans of its day.
Collectors are drawn to the W116 for its historical importance, timeless Bruno Sacco-influenced design, and legendary build quality. It's a usable classic that offers a driving experience far more modern than its age suggests. While all variants are respected, the 450 SEL 6.9 is the most sought-after model, representing the peak of 1970s performance and luxury in a discreet package. Its status as an engineering benchmark for Mercedes-Benz ensures its place in collections.
The market for the W116 is broad, with an average sale price around $15,000. This reflects a healthy supply of driver-quality cars that remain relatively accessible. At the top end, exceptional, low-mileage examples of the 450 SEL 6.9 can approach $100,000, while lesser models and project cars can be found for just a few thousand dollars. Values are stable but have been slowly climbing for well-documented, rust-free cars.
Buying Tips
- Rust is the primary concern; meticulously inspect the floor pans, jacking points, inner sills, wheel arches, and the areas around the front and rear windscreens.
- The complex hydropneumatic suspension on the 450 SEL 6.9 is expensive to repair. Ensure it functions correctly, doesn't leak, and doesn't sag at any corner.
- Bosch K-Jetronic fuel injection systems require expertise to tune and repair. Check for signs of poor running, hard starts, or rough idling.
- The vacuum-powered central locking system is a common failure point. Test all doors, the trunk, and the fuel filler door to ensure they lock and unlock properly.
- V8 models require timing chain replacement as a key maintenance item. A detailed service history is critical to verify this and other major work has been completed.
