About this car

This 2018 BMW 6 Series Gran Turismo M Sport has covered 53,863 miles, around 29,500 fewer than typical for its age. The dealer is asking £17,491, which is £100 below our market estimate of £17,591. To estimate its market asking price, we analyse UK dealer adverts for 71 BMW 6 Series Gran Turismo cars across different ages and specifications. Since we first spotted the advert 144 days ago, the asking price has dropped by £1,008. That history is worth bearing in mind when speaking to the dealer. MOT records show an expiry date of 7 April 2027, and the latest recorded mileage is consistent with the advert. The seller is Northridge Cars Hemel Hempstead, based in Hemel Hempstead.
