To estimate the price of the 2019 Ford Expedition XLT Ecoboost V6 3.5L XLT 4WD (Mid), I focused on the selling prices of similar cars. The most relevant data points are the 2020 Ford Expedition XLT 4WD (Mid) sold for 138,000 SAR on 2024-02-10 and the 2021 Ford Expedition XLT 4WD (Mid) sold for 171,000 SAR on 2024-08-06. The 2020 model with higher mileage (95,000 km) sold for 138,000 SAR, while the 2021 model with lower mileage (29,600 km) sold for 171,000 SAR. The 2019 model in question has 77,000 km, which is between these two. Considering the depreciation and mileage, the 2019 model should be valued slightly lower than the 2020 model due to its older age but higher than the 2017 model, which sold for 77,000 SAR. Therefore, I estimate the market price to be around 130,000 SAR.
