About this car

This 2020 BMW 4 Series M Sport has covered 36,439 miles, around 7,300 fewer than typical for its age. The dealer is asking £18,499, which is £1,004 below our market estimate of £19,503. To estimate its market asking price, we analyse UK dealer adverts for 1,749 BMW 4 Series cars across different ages and specifications. We first saw this car advertised 135 days ago. Its asking price has since fallen by £1,000. The time on sale and price change could be useful context when negotiating. MOT records show an expiry date of 30 March 2027, and the latest recorded mileage is consistent with the advert. It is advertised by Sandles Cars in Kings Lynn.

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 1,749 adverts of this make and model across different ages and specifications.

Advertised mileage is approximately 7,300 miles lower than typical for a 2020 BMW 4 Series.
