I started by looking at the selling price of a similar car: a 2015 Hyundai Accent I4 1.4L Kappa (Base) with 130000 km mileage, sold for SAR 27000 on 2023-12-08. Given that the car to be estimated has a slightly higher mileage of 138500 km, I adjusted the price downwards slightly. Next, I reviewed the listed prices of similar cars. The closest match was a car with the same mileage listed for SAR 29000, but since listed prices are generally higher than selling prices, I considered this as an upper limit. Other listed prices ranged from SAR 25000 to SAR 28000, with varying mileages. Taking into account the average condition and the fact that the car has not been sold yet, I estimated the market price to be slightly lower than the average of these listings but close to the actual selling price of the similar car sold in December 2023.
