Price and mileage comparison

Estimated market asking price: £19,954. The asking price is £45 above this estimate.

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 6,724 adverts of this make and model across different ages and specifications.

Advertised mileage is approximately 4,800 miles lower than typical for a 2021 BMW 3 Series.

181 other cars with the same year, trim, gearbox and fuel are for sale from £14,000 to £29,990.
