The estimate uses 544 UK dealer adverts for the Mercedes-Benz S Class, with adjustments for age, mileage, trim, engine and other specifications. Since we first spotted the advert 73 days ago, the asking price has dropped by £2,688. The time on sale and price change could be useful context when negotiating.
