About this car

With 57,000 miles on the clock, this 2021 Audi A3 S Line has done roughly 14,200 more miles than a typical 2021 Audi A3. At £12,999, it is advertised £4,138 below our estimated market asking price of £17,137. 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 143 days ago, the asking price has dropped by £1,000. That history is worth bearing in mind when speaking to the dealer. MOT records show an expiry date of 1 April 2027, and the latest recorded mileage is consistent with the advert. It is for sale at Field Way Motors in Gerrards Cross.

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