To estimate the price of the 2012 Audi A6 FSI V6 2.8L 45 TFSI Quattro (Top) with 253445 km mileage, I considered the following data points: 1. Selling prices of similar cars: 2014 Audi A6 2.8L V6 with 140850 km sold for AED 33900 on 2023-09-14 and another 2014 Audi A6 with 95000 km sold for AED 32000 on 2023-08-30. These cars are newer and have lower mileage, so their prices are higher. 2. Listed prices of similar cars: A 2012 Audi A6 FSI V6 2.8L with the same mileage is listed for AED 22000, and a 2014 Audi A6 2.8 Quattro V6 with 252000 km is listed for AED 29000. Considering the higher mileage and older model year of the target car, the price should be lower than these listings. 3. Depreciation logic: Assuming a 10% annual depreciation, the price of a 2012 model would be significantly lower than a 2014 model. Based on these factors, I estimated the market price.
