To estimate the price of the 2018 Ford Expedition XLT 4WD (Mid), I first considered the selling prices of similar cars. The 2020 XLT 4WD (Mid) sold for 138,000 SAR in February 2024, and the 2019 XLT 4WD (Mid) sold for 126,500 SAR in September 2024. These cars are newer and have lower mileage, so their prices are higher. The 2017 XLT (Base) sold for 77,000 SAR in September 2024, which is a lower trim. For 2018 models, listed prices were 117,000 SAR, 95,000 SAR, and 93,500 SAR, with mileages of 180,000 km, 141,415 km, and 185,132 km respectively. The car with 141,415 km is closest in mileage to the target car and is listed for 95,000 SAR. Considering the target car's mileage of 161,000 km and its condition, I estimate its market price to be slightly lower than the 95,000 SAR listing, as listings are often higher than actual selling prices.
