2020 Audi A8 cars for sale now, page 1 of 2
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. 15 of the 16 cars listed here meet these rules. Page 2 lists every other 2020 Audi A8 car, cheapest first, including the one 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 220 priced Audi A8 adverts on AskCar as of 5 November 2026. The figures on this page describe the cars advertised, not a valuation of every 2020 Audi A8.
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 2 cars whose advertised mileage is lower than the mileage recorded at their last MOT test.
