To estimate the price of the 2013 Ford Expedition V8 5.4L XLT (Base) with 236000 km mileage and average condition, I first looked at the selling prices of similar cars. The closest match is a car with the same variant and condition sold for 31000 SAR on 2024-01-02 with 271000 km. Another similar car with 281000 km sold for 30500 SAR on 2024-06-18. A car with 233000 km and a mid variant sold for 31000 SAR on 2024-04-20. Considering the mileage and condition, these prices suggest a range of 30500-31000 SAR. I also reviewed listed prices, where similar cars were listed between 28000 and 42000 SAR, but these are generally higher than actual selling prices. Therefore, I estimate the market price to be closer to the lower end of the selling prices range.
