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 789 adverts of this make and model across different ages and specifications.

Advertised mileage is approximately 6,300 miles lower than typical for a 2017 Audi A6 Avant.

Mileage concern: the advertised mileage is below the last MOT reading; ask the dealer to explain.
