About this car

This 2021 Audi A3 S Line is advertised with 42,000 miles on the clock. Our estimated market asking price is £15,611. This car is advertised at £14,950, which is £661 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 145 days ago, the asking price has dropped by £1,000. That history is worth bearing in mind when speaking to the dealer. Its recorded MOT is valid until 22 January 2027, and its advertised mileage is consistent with the latest MOT reading. It is advertised by Windmill Autos in Sandy.
