About this car

This 2021 Audi Q3 S Line is advertised with 98,485 miles, approximately 57,600 above the typical mileage for its age. Its asking price of £15,720 is £233 below our estimate of £15,953. To estimate its market asking price, we analyse UK dealer adverts for 3,470 Audi Q3 cars across different ages and specifications. The asking price is now £830 lower than when we first recorded the advert 152 days ago. That history is worth bearing in mind when speaking to the dealer. MOT records show an expiry date of 7 June 2027, and the latest recorded mileage is consistent with the advert. The seller is Evans Halshaw BYD Milton Keynes, based in Milton Keynes.
