About this car

The dealer is asking £23,490, which is £1,045 above our market estimate of £22,445. 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 96 days ago, and its asking price has since fallen by £1,500. That may be worth mentioning if you discuss the price with the dealer. MOT records show an expiry date of 1 June 2027, and the latest recorded mileage is consistent with the advert. It is advertised by Mazz Motors in Surbiton.
