To estimate the price of the 2015 Ford Fusion I4 2.5L SE (Mid) with 189000 km mileage, I first considered the actual selling price of a similar car with 186000 km mileage sold for SAR 16000 on 2024-03-18. This is the most reliable data point. Next, I looked at the listed prices of similar cars. The prices ranged from SAR 21000 to SAR 42000, but these are generally higher than actual selling prices. The closest listed price to the sold car was SAR 21000 for a car with 186000 km mileage, delisted on 2024-03-19. Considering the selling price and the listed prices, I estimated the market price to be slightly higher than the sold price but lower than the listed prices, accounting for the car's condition and mileage.
