About this car

This 2018 Mercedes-Benz G Class AMG has covered 41,586 miles, around 5,400 fewer than typical for its age. The dealer is asking £74,985, which is £8,533 below our market estimate of £83,518. We use UK dealer asking prices, including 408 Mercedes-Benz G Class listings, and account for the car’s age, mileage and specification. Since we first spotted the advert 71 days ago, the asking price has dropped by £5,000. That may be worth mentioning if you discuss the price with the dealer. MOT records show an expiry date of 2 April 2027, and the latest recorded mileage is consistent with the advert. It is advertised by The Car Factory in Blackburn.

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

Advertised mileage is approximately 5,400 miles lower than typical for a 2018 Mercedes-Benz G Class.
