To estimate the price of the 2015 Audi Q7 V6 3.0L 40 TFSI Sport (Mid) with 175000 km mileage and average condition, I considered the following data points: 1) A similar 2015 Audi Q7 3.0L V6 with 141500 km, average condition, and 40 TFSI Design (Top) variant sold for AED 50000 on 2023-10-10. 2) Another 2015 Audi Q7 3.0L TC V6 with 171000 km, average condition, and 40 TFSI (Base) variant sold for AED 36000 on 2023-10-22. 3) A 2015 Audi Q7 3.0L V6 TC with 190600 km, good condition, and 45 TFSI Sport S line (Mid+) variant sold for AED 35500 on 2023-12-17. 4) A 2015 Audi Q7 3.0L V6 SC with 180500 km, average condition, and 45 TFSI Sport S line (Mid+) variant sold for AED 34000 on 2024-05-21. Considering the target car's mileage and condition, I weighted the prices of similar cars, especially those with average condition and similar mileage. The most relevant data points are the first two, with prices of AED 50000 and AED 36000, respectively. Given the target car's mid variant and mileage, I estimated the price to be slightly lower than the top variant but higher than the base variant.
