About this car

This 2018 BMW 4 Series M Sport has covered 49,000 miles, around 13,800 fewer than typical for its age. At £15,996, it is advertised £63 above our estimated market asking price of £15,933. To estimate its market asking price, we analyse UK dealer adverts for 1,722 BMW 4 Series cars across different ages and specifications. Since we first spotted the advert 72 days ago, the asking price has dropped by £754. That may be worth mentioning if you discuss the price with the dealer. Its recorded MOT is valid until 27 December 2026, and its advertised mileage is consistent with the latest MOT reading. It is for sale at Dave Fox Cars in Stone.

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 1,722 adverts of this make and model across different ages and specifications.

Advertised mileage is approximately 13,800 miles lower than typical for a 2018 BMW 4 Series.

The advertised mileage is consistent with the last MOT reading.
