About this car

This 2021 Audi A3 S Line has covered 25,845 miles, around 16,900 fewer than typical for its age. Our estimated market asking price is £18,531. This car is advertised at £17,640, which is £891 below that figure. We use UK dealer asking prices, including 6,484 Audi A3 listings, and account for the car’s age, mileage and specification. Since we first spotted the advert 83 days ago, the asking price has dropped by £1,140. That history is worth bearing in mind when speaking to the dealer. MOT records show an expiry date of 4 June 2027, and the latest recorded mileage is consistent with the advert. The seller is Big Motoring World Peterborough, based in Peterborough.
