About this car

This 2015 Mercedes-Benz SLK AMG Sport is advertised with 66,036 miles, approximately 12,400 above the typical mileage for its age. The dealer is asking £8,449, which is £598 below our market estimate of £9,047. We use UK dealer asking prices, including 398 Mercedes-Benz SLK listings, and account for the car’s age, mileage and specification. Since we first spotted the advert 141 days ago, the asking price has dropped by £550. The time on sale and price change could be useful context when negotiating. MOT records show an expiry date of 28 January 2027, and the latest recorded mileage is consistent with the advert. The seller is Noya Motor Group, based in Peterborough.
