We use UK dealer asking prices, including 775 Audi A6 Avant listings, and account for the car’s age, mileage and specification. Since we first spotted the advert 148 days ago, the asking price has dropped by £1,200. Our records show an MOT expiry date of 20 September 2026, which has passed. Ask the dealer for an update.
