About this car

This car is advertised at £20,000, which is £2,830 below that figure. We use UK dealer asking prices, including 544 Mercedes-Benz S Class listings, and account for the car’s age, mileage and specification. Since we first spotted the advert 150 days ago, the asking price has dropped by £1,950. The time on sale and price change could be useful context when negotiating. MOT records show an expiry date of 27 April 2027, and the latest recorded mileage is consistent with the advert. The seller is Car Firm Peterborough, based in Peterborough.
