To estimate its market asking price, we analyse UK dealer adverts for 6,484 Audi A3 cars across different ages and specifications. Since we first spotted the advert 145 days ago, the asking price has dropped by £1,200. Ask the dealer why the advert shows fewer miles than the 54,172 recorded at the latest MOT. Its MOT is recorded as valid until 2 June 2027. You can find this car at Auto Unit in Newport.

Price and mileage comparison

Estimated market asking price: £15,041. The asking price is £249 above this estimate.

The estimate uses UK dealer asking prices, accounting for make, model, trim, version, age, mileage, fuel, gearbox, body type, driven wheels, engine size and power. It estimates an advertised price, not a confirmed sale price.

The pricing calculation includes 6,484 adverts of this make and model across different ages and specifications.

Advertised mileage is approximately 10,200 miles higher than typical for a 2021 Audi A3.

Mileage concern: the advertised mileage is below the last MOT reading; ask the dealer to explain.
