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

Advertised mileage is approximately 33,000 miles higher than typical for a 2018 BMW 8 Series.

The advertised mileage is consistent with the last MOT reading.
