To estimate the price of the 2023 Ford Expedition EL XLT 4WD (Mid+), I first looked at the selling prices of similar used cars. The 2021 Ford Expedition XLT 4WD (Mid) with similar specs and conditions sold for SAR 167500, SAR 175000, and SAR 171000 in late 2023 and mid-2024. These cars had lower mileage (between 29600 km and 44000 km) compared to the target car's 100000 km. Given the higher mileage of the target car, I adjusted the price downwards. The average selling price of these cars is SAR 171833. Considering the higher mileage, I applied a depreciation factor. Additionally, I checked the new car prices for 2025 models, where the closest variant, the XLT AWD, starts at SAR 234600. Applying a 10% annual depreciation for one year, the estimated value for a 2023 model would be around SAR 211140. Combining these insights, I arrived at the final estimate.
