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 1,138 adverts of this make and model across different ages and specifications.

Advertised mileage is approximately 39,700 miles lower than typical for a 2018 BMW 4 Series Gran Coupe.
