We use UK dealer asking prices, including 1,862 Audi A5 listings, and account for the car’s age, mileage and specification. The asking price is now £1,000 lower than when we first recorded the advert 145 days ago. That may be worth mentioning if you discuss the price with the dealer.

The estimate uses UK dealer asking prices, accounting for make, model, trim, version, age, mileage, fuel, gearbox, body type, driven wheels, engine size and power. It estimates an advertised price, not a confirmed sale price.

The pricing calculation includes 1,862 adverts of this make and model across different ages and specifications.

Advertised mileage is approximately 47,000 miles lower than typical for a 2018 Audi A5.

The advertised mileage is consistent with the last MOT reading.
