About this car

At £23,990, it is advertised £202 above our estimated market asking price of £23,788. Our estimate draws on 876 Mercedes-Benz GLB adverts across the UK, adjusting for age, mileage, trim, engine and other specifications. We first recorded this advert 81 days ago, and its asking price has since fallen by £1,009. That history is worth bearing in mind when speaking to the dealer. MOT records show an expiry date of 11 November 2026, and the latest recorded mileage is consistent with the advert.

The pricing calculation includes 876 adverts of this make and model across different ages and specifications.

Advertised mileage is approximately 20,700 miles lower than typical for a 2020 Mercedes-Benz GLB.
