To estimate the price of the 2014 Ford Expedition V8 5.4L XLT (Base) with 226297 km mileage, I first looked at the selling price of a similar car sold on 2024-04-26 for SAR 51500 with 188000 km. Given the higher mileage of the target car, I adjusted the price downwards. Next, I reviewed listed prices of similar cars: SAR 50000 (226297 km), SAR 44000 (227000 km), SAR 66000 (222000 km), SAR 38000 (220000 km), SAR 50000 (215000 km), and SAR 43000 (243300 km). The average of these listed prices is approximately SAR 48500. Considering the car's average condition and the fact that listed prices are generally higher than selling prices, I adjusted the estimate slightly lower than the average listed price but higher than the lowest selling price to reflect a realistic market value.
