To estimate the price of the 2018 Ford Expedition XLT V6 3.5L Turbocharged XLT 4WD, I first considered the selling prices of similar cars. The 2019 Ford Expedition XLT 4WD (Mid) with 77,000 km sold for 126,500 SAR on 2024-09-21. The 2020 model with similar specs sold for 138,000 SAR on 2024-02-10. The 2016 model with higher mileage (163,500 km) sold for 71,500 SAR on 2023-05-14. The 2017 model with 120,000 km sold for 77,000 SAR on 2024-09-10. These prices suggest a depreciation trend. The 2018 model listed prices are around 95,000 SAR, with one delisted at 108,000 SAR. Considering the 2018 model's mileage of 180,000 km, which is higher than the 2019 and 2020 models, and the fact that it is in good condition, I estimate the market price to be slightly lower than the listed prices, around 90,000 SAR.
