About this car

This 2018 Mercedes-Benz GLA has covered 127,000 miles, around 62,200 more miles than is typical for its age. Priced at £8,495, it is advertised £449 below the AskCar estimate of £8,944. The AskCar estimate uses UK dealer asking prices, including 2,548 Mercedes-Benz GLA adverts, and accounts for the car’s age, mileage and specification. We first saw this car advertised 79 days ago. Its asking price has since fallen by £655. That history is worth bearing in mind when speaking to the dealer. The latest MOT record shows an expiry date of 21 December 2026, with the advertised mileage consistent with the recorded reading. It is advertised by German Cars in Weston-Super-Mare.
