About this car

This 2021 Audi A3 S Line has covered 65,324 miles, around 22,300 more than typical for its age. The dealer is asking £15,498, which is £536 below our market estimate of £16,034. Our estimate draws on 6,542 Audi A3 adverts across the UK, adjusting for age, mileage, trim, engine and other specifications. We first recorded this advert 72 days ago, and its asking price has since fallen by £1,000. That history is worth bearing in mind when speaking to the dealer. MOT records show an expiry date of 29 March 2027, and the latest recorded mileage is consistent with the advert. The seller is Arnold Clark Mercedes-Benz of Grangemouth, based in Grangemouth.
