My GarageUsed Mercedes-Benz S-Class Buying Guide
The S-Class is Mercedes' flagship and one of the most technologically advanced sedans ever built. Depreciation is steep, which means used-market values can be extraordinary — but ownership complexity is also extraordinary.
Best Years to Buy
Generations with the strongest long-term reputation.
V8 is well-understood; parts and independent-mechanic support are strong.
Later production refined; V8 is preferred for long-term ownership.
Years to Research Carefully
Not deal-breakers — but they reward a careful buyer.
Active Body Control is refined but expensive when it fails.
Exceptional cars but very expensive to service; verify complete history.
