About the Mercedes-Benz S Class
The S Class has been Mercedes-Benz's flagship saloon since 1972, setting benchmarks for luxury, innovation and refinement. The W221 generation (2005-2013) introduced advanced safety systems and powerful engine options, whilst the W222 (2013-2020) brought semi-autonomous driving technology and unparalleled interior quality. The current W223 generation launched in 2021 with revolutionary MBUX infotainment and Level 3 autonomous capability.
Engine options span from efficient diesel variants like the S350d to powerful petrols including the S500 and performance-focused AMG models. Long wheelbase versions offer exceptional rear passenger space, making the S Class a favourite among chauffeur services and executives alike. Standard equipment includes air suspension, leather upholstery, and comprehensive driver assistance systems.
What Affects the Price
Age and mileage are primary factors, with newer W222 models commanding premium prices whilst W221 examples have depreciated significantly. Specification matters considerably—long wheelbase variants, AMG Line packages, panoramic sunroofs and rear entertainment systems all add value. Full Mercedes-Benz service history is essential for maintaining residual values.
Engine choice impacts pricing, with S350d diesel models popular for their economy and performance balance, whilst V8 petrol variants attract enthusiasts but cost more to run. Colour combinations affect desirability—black, silver and white exterior colours with black or beige leather interiors sell fastest. High mileage examples below 100,000 miles can represent excellent value if properly maintained, as S Class models are engineered for longevity.
Buying Tips
Verify complete service history, preferably with Mercedes-Benz main dealers, as these cars require specialist maintenance. Check the AIRMATIC air suspension thoroughly—listen for compressor noise and ensure the ride height adjusts correctly, as repairs can exceed £2,000 per corner. Inspect all electronic systems including seat adjustments, massage functions and infotainment, as faults are expensive to rectify.
Examine for oil leaks, particularly from the engine and gearbox, which are common on higher-mileage examples. Test all driver assistance features including adaptive cruise control, lane keeping and parking systems. Request evidence of cambelt changes on relevant engines and check for software updates. Consider models with remaining manufacturer warranty or purchase an extended warranty given the complexity of these vehicles. Budget for annual running costs including insurance, road tax and premium fuel or AdBlue.
