What owners say about this generation
Our take, from owner reports

The version owners recommend
2010-2011 S550 (naturally aspirated M273 V8, RWD). Owners consistently point to these model years as the most reliable and cost-effective to own long-term, avoiding the turbocharged V8s of the W222 and the expensive ABC suspension and V12 complications of the AMG models.
Competitors to consider
Owners compare it most often with the Lexus LS400, Lexus LS460, Porsche Panamera, Mercedes-Benz E-class (W211, W212) and Mercedes-Benz CLS-class (W219).

Overall sentiment
Owners consistently describe the W221 S-class as a magnificent highway cruiser with a magic-carpet ride and unmistakable road presence, but they overwhelmingly warn that it is an extremely expensive car to maintain. The dominant sentiment is that the purchase price is deceptive: buyers should expect to spend thousands annually on repairs, with many stating the car will "eat your money." There is a clear consensus that the post-facelift models (2010-2013) are significantly more reliable than the early 2007-2009 cars, with the naturally aspirated M273 V8 and 7G-Tronic drivetrain being the most recommended combination. Owners strongly advise against buying one without a thorough pre-purchase inspection, a documented service history, and a substantial repair budget.
Positioning vs competitors
Owners position the W221 as having superior highway ride comfort and a more distinctive, flagship presence than the Lexus LS or the E-class, but they consistently note that the Lexus LS is far more reliable and cheaper to maintain. The Porsche Panamera is mentioned as a potential alternative, with one experienced owner stating the W221 was "not cheap to maintain relative to a Panamera." The W219 CLS is recommended as a more maintainable, E-class-based alternative for those on a tighter budget. Within the S-class lineage, the W221 is seen as a step down in build quality from the W140 and W126, with owners noting "cut corners" compared to those earlier generations.
Recommended configurations
Owners strongly recommend the 2010-2013 S550 with the naturally aspirated 5.5L M273 V8 and the 7G-Tronic transmission. They advise avoiding all AMG models (S63, S65) due to "All Money Gone" repair costs, and any car equipped with ABC (Active Body Control) suspension, which is described as a "literal death wish" for the wallet. The long-wheelbase version is recommended if regularly carrying more than two passengers. A pre-purchase inspection by a Mercedes-specific independent shop is considered mandatory.
General recommendations
This generation is best suited to buyers who can afford S-class maintenance costs, have a dedicated repair budget (often cited as $10,000+ set aside), and either have a trusted independent Mercedes specialist or are capable of DIY repairs. Owners strongly recommend buying a post-facelift model (2010-2013) over the pre-facelift (2007-2009), which are described as "disgustingly unreliable." A documented service history is non-negotiable. The car should be inspected for airmatic suspension condition, as struts have a finite lifespan of about 8 years regardless of mileage. Owners also warn that even with a good example, one should expect to replace motor mounts, alternator, starter, thermostat, and radiator over time.
Remarks
The W221 is widely praised for its distinctive, brutalist exterior design, which owners feel is unmistakably an S-class, unlike the later W222 which some describe as looking like a "long E-class." The post-facelift models with LED running lights are particularly favored. Owners note that the car is very large and may be a tight fit in standard residential garages. The interior is considered well-equipped even by modern standards, with features like massage seats and cooled seats.
