The MERCEDES-BENZ S CLASS (2017-20) is a luxury saloon, sitting near the top of the UK market for comfort, refinement and prestige. It is designed for buyers who want a spacious, quiet executive car rather than a hatchback or SUV, and competes with the BMW 7 Series and Audi A8. On mycarcheck.com, this model has generated 11,380 checks covering 3,216 distinct VINs, a substantial sample. Checked cars averaged 59,000 miles and 1.34 previous keepers, while annual mileage averaged 13,000. The average private-sale valuation was £35,800, useful context when assessing a used S-Class, though condition and history still matter to buyers. The S-Class is best suited to executives, motorway travellers and families who value rear-seat room and a calm, comfortable journey. Its cabin, sense of occasion and quiet ride are strengths, making it a more indulgent choice than rivals. Running costs can be high, so check service records and budget carefully.
