2023 BMW 3 Series cars for sale now, page 1 of 9

This page picks out up to 10 cars in each of these groups: best value, cheapest, lowest mileage, recently reduced and newly advertised. 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. 440 of the 446 cars listed here meet these rules. Pages 2 to 9 list every other 2023 BMW 3 Series car, cheapest first, including the 6 the groups do not pick from.

The AskCar estimate is our expected asking price for that one car, from its model, age, mileage and specification, using the 6,862 priced BMW 3 Series adverts on AskCar as of 4 November 2026. The figures on this page describe the cars advertised, not a valuation of every 2023 BMW 3 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.
