To estimate the price of the 2015 Audi Q7 35 TFSI Quattro V6 3.0L Turbocharged 45 TFSI (Base), I first considered the selling prices of similar cars. The closest match is a 2015 Audi Q7 TFSI Quattro V6 3.0L Turbocharged with a 55 TFSI (Top) variant, which sold for SAR 75000 in May 2024 with 107000 km. Another similar car, a 2015 Audi Q7 V6 3.0L with a 55 TFSI (Top) variant, sold for SAR 70000 in August 2023 with 140000 km. These cars are in good condition and have lower mileage than the target car. The target car has higher mileage (155255 km) and is in average condition, which would decrease its value. Additionally, a 2016 Audi Q7 with a 45 TFSI S-Line (Mid) variant sold for SAR 72500 in March 2024 with 101000 km, but it is a newer model. The listed price for a similar 2015 Audi Q7 45 TFSI (Base) with 141394 km is SAR 52000, which is likely higher than the actual selling price. Considering these factors, the estimated market price for the target car is adjusted downwards from the selling prices of the higher variant cars due to its higher mileage and average condition.
