About this car

This 2021 Mercedes-Benz S Class AMG Line Premium has covered 28,582 miles, around 11,200 fewer than typical for its age. At £51,990, it is advertised £8,619 below our estimated market asking price of £60,609. To estimate its market asking price, we analyse UK dealer adverts for 544 Mercedes-Benz S Class cars across different ages and specifications. We first saw this car advertised 150 days ago. Its asking price has since fallen by £4,850. That may be worth mentioning if you discuss the price with the dealer. MOT records show an expiry date of 19 March 2027, and the latest recorded mileage is consistent with the advert. The seller is Evans Halshaw BYD Rotherham, based in Rotherham.
