About this car

This 2018 Audi A6 Saloon S Line has covered 24,000 miles, around 46,300 fewer than typical for its age. At £19,995, it is advertised £142 below our estimated market asking price of £20,137. We use UK dealer asking prices, including 858 Audi A6 Saloon listings, and account for the car’s age, mileage and specification. Since we first spotted the advert 132 days ago, the asking price has dropped by £1,000. That may be worth mentioning if you discuss the price with the dealer. MOT records show an expiry date of 10 May 2027, and the latest recorded mileage is consistent with the advert. It is for sale at OC Davies & Son in Carmarthen.
