About this car

The advertised mileage for this 2023 BMW 4 Series M Sport is 29,041 miles. At £25,990, it is advertised £2,330 below our estimated market asking price of £28,320. We use UK dealer asking prices, including 1,758 BMW 4 Series listings, and account for the car’s age, mileage and specification. The asking price is now £2,000 lower than when we first recorded the advert 81 days ago. That may be worth mentioning if you discuss the price with the dealer. MOT records show an expiry date of 20 January 2027, and the latest recorded mileage is consistent with the advert. The seller is Stratstone BMW Milton Keynes, based in Milton Keynes.
