The most relevant data point is the 2020 Audi A8 3.0L TFSI sold by a dealer for AED 178495.75 on 2023-10-31. This car is very similar in year, engine size, and specifications to the car we are estimating. The mileage of the sold car is 55553 km, which is lower than the 68000 km of the car in question, suggesting a slightly lower value for the car we are estimating. The listed prices of similar 2019 models with higher mileage and different variants range from AED 140000 to AED 220000, but these are not actual selling prices and are generally higher than market value. Considering the depreciation and the fact that the car in question has higher mileage than the sold car, the estimated market price should be slightly lower than AED 178495.75.
