About this car

This 2020 Mercedes-Benz GLS AMG Line Premium Plus is advertised with 60,000 miles on the clock. At £46,989, it is advertised £2,395 above our estimated market asking price of £44,594. Our estimate draws on 130 Mercedes-Benz GLS adverts across the UK, adjusting for age, mileage, trim, engine and other specifications. The asking price is now £1,000 lower than when we first recorded the advert 112 days ago. That history is worth bearing in mind when speaking to the dealer. MOT records show an expiry date of 15 April 2027, and the latest recorded mileage is consistent with the advert. The seller is Blackstone Motors, based in White City.

Price and mileage comparison

Estimated market asking price: £44,594. The asking price is £2,395 above this estimate.

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 130 adverts of this make and model across different ages and specifications.

The advertised mileage is consistent with the last MOT reading.
