Conclusion
The 2020 Mercedes-Benz S-Class delivers one of the finest interiors ever built, combining craftsmanship, innovation, and comfort in a way few cars match 5. However, its reliability is inconsistent: while initial build quality scores highly, long-term ownership brings elevated risks and costs. If you value technological luxury and can absorb high maintenance expenses, the W222 interior makes a compelling choice. If long-term reliability and low running costs are your priority, consider alternatives like the Lexus LS or even a newer Genesis G90. Always conduct thorough inspections and secure an extended warranty when purchasing.
