The Mercedes-Benz W221 S-Class, sold from 2006 to 2013 in North America, was a return to form for the brand's flagship sedan. It replaced the W220 with a more imposing design featuring prominent fender flares and a focus on high-quality materials. The W221 was a technological showcase, introducing features like Night View Assist, Distronic Plus with Pre-Safe braking, and an updated COMAND infotainment system. Powertrain options ranged from the S350 V6 to the S550 V8, the twin-turbo V12 S600, and the high-performance S63 and S65 AMG models.
Collectors appreciate the W221 for being one of the last S-Class generations to blend modern technology with a more traditional luxury feel. It offers a driving experience that's comfortable and isolated but still connected. The high-performance AMG variants are the most desirable, especially the S65 with its 604 hp twin-turbo V12. The non-AMG S600 is also sought after for its smooth, powerful V12 and luxurious appointments.
With an average sale price under $20,000, the W221 market has reached the bottom of its depreciation curve, making it a compelling value. While top-tier, low-mileage AMG and S600 models can sell for over $60,000, the vast majority of cars trade for much less. This affordability is balanced by the potential for high maintenance costs, which keeps values in check but makes well-maintained examples a smart buy for enthusiasts.
Buying Tips
- The Airmatic suspension is a common failure point. Check for sagging corners and listen for a constantly running compressor, as repairs are costly.
- Insist on a pre-purchase inspection that includes a scan with a Mercedes-Benz Star Diagnostic System. It can reveal hidden electronic faults in the COMAND system, driver aids, and other modules.
- On 2007-2011 S550 models with the M273 V8, check for records of the balance shaft sprocket being replaced, as it's a known and expensive engine-out repair.
- V12 models (S600 and S65) can suffer from ignition coil pack failures. Each of the two packs costs thousands to replace, so verify their condition and age.
- A complete and verifiable service history is non-negotiable. Deferred maintenance on a W221 can quickly turn an affordable luxury car into an expensive project.
