I started by looking at the selling prices of similar cars. The first car, a 2015 Kia Rio I4 1.4L sedan with 226000 km mileage, sold for SAR 17000 on 2024-03-05. The second car, a 2015 Kia Rio I4 1.4L hatchback with 187500 km mileage, sold for SAR 17000 on 2024-06-02. Both cars are of the same variant (LX Base) and similar condition. Given the target car is a hatchback with 209000 km mileage, I considered the selling price of the second car as more relevant. Next, I reviewed the listed prices. The closest match is a 2015 Kia Rio I4 1.4L hatchback with 209000 km listed for SAR 24000. However, listed prices are generally higher than selling prices. Other listed prices for similar cars range from SAR 19000 to SAR 29500, but these are for different mileages and body types. Considering the selling prices and the listed price of the closest match, I estimated the market price of the target car to be slightly higher than the selling prices but lower than the listed price.
