I started by looking at the selling prices of similar cars. The most relevant data points are the cars sold in late 2023 and early 2024. The selling prices for cars with similar mileage and condition ranged from SAR 20,000 to SAR 25,000. Specifically, cars with higher mileage (around 189,000 km) sold for SAR 25,000, while those with lower mileage (132,000 km to 147,000 km) sold for SAR 20,000 to SAR 21,000. The car in question has a mileage of 177,000 km, which is closer to the higher mileage cars that sold for SAR 25,000. I also considered the listed prices, which ranged from SAR 21,000 to SAR 32,000, but these are generally higher than actual selling prices. Given the car's mileage and condition, I estimated the price to be slightly lower than the highest selling price but higher than the lower mileage cars.
