About this car

With 40,000 miles on the clock, this 2017 Mercedes-Benz SL AMG Line has done roughly 8,500 more miles than a typical 2017 Mercedes-Benz SL. The dealer is asking £32,990, which is £1,617 above our market estimate of £31,373. To estimate its market asking price, we analyse UK dealer adverts for 365 Mercedes-Benz SL cars across different ages and specifications. We first recorded this advert 102 days ago, and its asking price has since fallen by £1,000. That history is worth bearing in mind when speaking to the dealer. MOT records show an expiry date of 30 June 2027, and the latest recorded mileage is consistent with the advert. It is advertised by Gerry Hill Car Sales in Aberdare.

The estimate uses UK dealer asking prices, accounting for make, model, trim, version, age, mileage, fuel, gearbox, body type, driven wheels, engine size and power. It estimates an advertised price, not a confirmed sale price.

The pricing calculation includes 365 adverts of this make and model across different ages and specifications.

Advertised mileage is approximately 8,500 miles higher than typical for a 2017 Mercedes-Benz SL.
