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 140 adverts of this make and model across different ages and specifications.

Advertised mileage is approximately 12,100 miles higher than typical for a 2018 BMW 3 Series Gran Turismo.

The advertised mileage is consistent with the last MOT reading.
