This car is advertised at £27,200, which is £874 below that figure. Our estimate draws on 1,725 BMW 4 Series adverts across the UK, adjusting for age, mileage, trim, engine and other specifications. We first recorded this advert 117 days ago, and its asking price has since fallen by £2,452. That history is worth bearing in mind when speaking to the dealer.
