About this car

This 2018 BMW 6 Series M Sport has covered 25,000 miles. Our estimated market asking price is £30,066. This car is advertised at £27,990, which is £2,076 below that figure. Our estimate draws on 158 BMW 6 Series adverts across the UK, adjusting for age, mileage, trim, engine and other specifications. We first recorded this advert 127 days ago, and its asking price has since fallen by £2,000. The last MOT shows 25,708 miles, more than the advert. This is worth checking with the dealer. The latest recorded MOT expires on 15 June 2027. It is advertised by LTV in Bury.

How we estimate prices and check cars

Price and mileage comparison

Estimated market asking price: £30,066. The asking price is £2,076 below 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 158 adverts of this make and model across different ages and specifications.

Advertised mileage is approximately 21,300 miles lower than typical for a 2018 BMW 6 Series.

Mileage concern: the advertised mileage is below the last MOT reading; ask the dealer to explain.
