Detailed Explanations
2007-2009 (W221): The Classic S-Class
These early W221 models offer a classic S-Class experience at a more accessible price point. While reliable with proper maintenance, they are older vehicles and may require more frequent upkeep. The COMAND system is less advanced than later models, and air suspension issues are a known potential problem. Consider these years if you're looking for a comfortable and luxurious ride on a budget, but be prepared for potential maintenance costs associated with an older luxury car.
2010-2013 (W221 Facelift): A Step Up
The facelifted W221 models brought significant improvements, including an updated COMAND system, refreshed styling, and enhanced safety features. The interior also received some refinements. While these models are generally more desirable than the earlier W221s, air suspension issues remain a possibility, and the increased complexity can lead to higher repair costs. This generation offers a good balance of luxury, features, and price.
2014-2017 (W222): Modern Luxury
The W222 generation marked a significant leap forward in design, technology, and luxury. These models boast a modern aesthetic, a lavish interior, and advanced features like Magic Body Control (optional). The engine options are powerful and efficient. However, the higher price point and complex electronic systems can lead to expensive repairs. While air suspension issues are less common than in previous generations, they can still occur. This is a great choice for those who prioritize modern features and are willing to pay for the associated maintenance.
2018-2020 (W222 Facelift): The Pinnacle of S-Class
The facelifted W222 models represent the pinnacle of S-Class luxury. They feature enhanced technology, including dual 12.3-inch displays and improved driver-assistance systems, along with more powerful engine options and an even more refined ride. However, they also come with the highest price tag and the most complex electronics, increasing the potential for failures and expensive repairs. Depreciation can also be significant. If you want the absolute best and are prepared for the associated costs, this is the generation to choose.

The chrome accents and overall silhouette exude sophistication and class, making it a visually appealing option for buyers seeking a classic S-Class look.
Relatively Lower Price Point (2007-2009):
Due to their age, the 2007-2009 S550 models are available at a significantly lower price point compared to newer generations.
