This page picks out up to 10 cars in each of these groups: best value, cheapest, lowest mileage and recently reduced. A car in more than one group is listed in full once. The groups pick only from cars with photos and an AskCar estimate, priced at £500 or more and no more than 25% under that estimate. All 6 cars listed here meet these rules.

The AskCar estimate is our expected asking price for that one car, from its model, age, mileage and specification, using the 165 priced BMW 6 Series adverts on AskCar as of 7 November 2026. The figures on this page describe the cars advertised, not a valuation of every 2018 BMW 6 Series.

Each car: year, make, model, engine and trim, power, gearbox, fuel, body, doors, colour; mileage; price and its changes; how the price compares with the AskCar estimate; emissions standard and ULEZ compliance where it holds; MOT; dealer and town; AskCar page. Each car's AskCar page has its full price history and cheaper cars like it.

This list leaves out 1 car whose advertised mileage is lower than the mileage recorded at its last MOT test.
