The car in question is a 2011 Audi A6 V6 3.0L Supercharged AWD 45 TFSI Quattro. There is no direct selling price data available for similar cars, so I will use the new car prices and the classified ad listing to estimate the price. The new 2025 Audi A6 45 TFSI Quattro starts at AED 234045. Assuming a 10% annual depreciation, the car would have depreciated for 13 years. The depreciation factor is approximately 0.25 (0.9^13). Applying this to the new car price gives an estimated value of around AED 58511. However, the classified ad for a 2012 Audi A6 with similar specs lists the car at AED 37000. Considering the ad price is likely higher than the actual selling price, and the car in question is a year older, I estimate the market price to be slightly lower than the ad price.
