I started by looking at the actual selling price of a similar car, which was SAR 38000 on 2024-06-13. This is the most reliable data point. Next, I reviewed the listed prices of similar cars. The prices ranged from SAR 36000 to SAR 45000, with the closest match being SAR 40500. Given that listed prices are generally higher than selling prices, I considered the lower end of the range. The car in question has the same mileage and condition as the sold car, so I used the selling price as the primary reference and adjusted slightly based on the listed prices.
