The most relevant data point is the selling price of a 2020 Audi A8 L 55 TFSI Quattro V6 3.0L Turbocharged with the same variant and similar mileage, which sold for SAR 195,000 in June 2024. This car is one year older than the target car, so we can expect the 2021 model to be slightly higher in value. The listed prices for similar 2020 and 2022 models range from SAR 210,000 to SAR 259,000, indicating that the market values these cars higher than the selling price. Considering the depreciation and the fact that the target car is a 2021 model, a reasonable estimate would be slightly above the 2020 selling price but below the 2022 listed price.
