To estimate the price of the 2023 Hyundai Sonata I4 2.5L Smart (Mid) with 18200 km mileage, I first considered the selling prices of similar cars. A similar car with 13000 km sold for 94500 SAR in July 2024, and another with 87760 km sold for 69000 SAR in October 2024. The car with 13000 km is very close in mileage and condition, suggesting a price around 94500 SAR. The car with higher mileage sold for significantly less, indicating depreciation with higher mileage. I also looked at listed prices: a car with 13000 km was listed for 94500 SAR, and another with 26000 km for 91000 SAR. These listings support the selling price of 94500 SAR for lower mileage cars. Considering the target car's mileage of 18200 km, which is closer to 13000 km than 26000 km, I estimate the market price slightly lower than 94500 SAR to account for the additional mileage.
