To estimate the price of the 2017 Ford Edge V6 3.5L Ambiente (Base) with 171000 km mileage, I first considered the selling price of a similar 2016 Ford Edge V6 3.5L Trend (Mid) with 94000 km mileage, which sold for SAR 59000 in September 2023. Given the higher mileage of the target car, I adjusted the price downwards. Next, I looked at listed prices of similar cars: a 2017 Ford Edge V6 3.5L Ambiente (Base) with the same mileage listed for SAR 58000, and a 2016 Ford Edge V6 3.5L Ambiente (Base) with 194000 km listed for SAR 49000. Considering the target car's mileage and condition, I estimated its market price to be slightly lower than the listed price of the 2017 model but higher than the 2016 model with higher mileage.
