I started by looking at the selling prices of similar used cars. The closest match is the 2020 Ford Expedition XLT V6 3.5L Turbocharged with 45000 km sold for 144000 SAR on 2023-07-08. Adjusting for higher mileage (140500 km vs 45000 km), I applied a depreciation factor. Another close match is the 2020 Ford Expedition V6 3.5L Turbo Charge with 95000 km sold for 138000 SAR on 2024-02-10. Considering the higher mileage of the target car, I adjusted the price downwards. The 2019 Ford Expedition XLT V6 3.5L Ecoboost with 77000 km sold for 126500 SAR on 2024-09-21 also provided a reference point, but the target car is a year newer. Factoring in these data points and the higher mileage, I estimated the market price accordingly.
