About this car

This 2017 Mercedes-Benz SL AMG Line is advertised with 13,968 miles, approximately 17,500 below the typical mileage for its age. At £35,750, it is advertised £654 below our estimated market asking price of £36,404. We use UK dealer asking prices, including 365 Mercedes-Benz SL listings, and account for the car’s age, mileage and specification. Since we first spotted the advert 95 days ago, the asking price has dropped by £700. That history is worth bearing in mind when speaking to the dealer. MOT records show an expiry date of 8 March 2027, and the latest recorded mileage is consistent with the advert. You can find this car at Adams & Sons in Oakham.
