To estimate the price of the 2014 Ford Expedition V8 5.4L XLT 4WD (Mid) with 171,000 km mileage, I first considered the selling prices of similar cars. The most relevant data point is a similar car with the same variant and good condition, sold for SAR 45,000 on 2024-08-04 with 149,000 km. Given the target car's higher mileage, a slight reduction in value is expected. Other selling prices for the base variant with average condition ranged from SAR 31,000 to SAR 51,500, with mileage between 158,000 and 188,000 km. The listed prices for the same variant ranged from SAR 45,000 to SAR 65,000, but these are generally higher than actual selling prices. Considering the target car's good condition and mileage, I estimate its market price slightly below the SAR 45,000 selling price of the similar car with lower mileage.
