Price and mileage comparison

Estimated market asking price: £19,268. The asking price is £273 below this estimate.

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 3,457 adverts of this make and model across different ages and specifications.

Advertised mileage is approximately 800 miles higher than typical for a 2020 Audi Q3.

The advertised mileage is consistent with the last MOT reading.

The recorded MOT has expired; ask the dealer for an up-to-date MOT.
