I started by examining the selling prices of similar cars. The most relevant data points are the 2012 Ford Fusion I4 2.5L S (Base) with 151,000 km sold for 16,500 SAR and 17,000 SAR in early 2024. Another similar car with higher mileage (228,000 km) sold for 14,000 SAR in late 2023. These prices suggest a range of 14,000 to 17,000 SAR for cars in average condition. The car in question has lower mileage (125,000 km), which should increase its value slightly compared to these examples. I also considered the listed prices, which are generally higher than selling prices. A similar car was listed for 21,500 SAR but was delisted, indicating it likely sold for less. Considering these factors, I estimate the market price to be slightly above the highest selling price due to the lower mileage, settling at 17,500 SAR.
