About this car

This 2021 Audi A4 S Line is advertised with 26,233 miles, approximately 24,000 below the typical mileage for its age. At £19,693, it is advertised £721 below our estimated market asking price of £20,414. To estimate its market asking price, we analyse UK dealer adverts for 1,429 Audi A4 cars across different ages and specifications. The asking price is now £1,679 lower than when we first recorded the advert 145 days ago. That history is worth bearing in mind when speaking to the dealer. MOT records show an expiry date of 2 November 2026, and the latest recorded mileage is consistent with the advert. It is for sale at Cargem in Rainham.
