To estimate the price of the 2023 Hyundai Accent I4 1.4L Kappa (Base) with 30000 km mileage in average condition, I first considered the actual selling price of a similar car with 22000 km mileage sold for SAR 51000 on 2024-03-21. Given the similar condition and specs, this is a strong reference point. Next, I looked at listed prices: one with 38000 km listed for SAR 42001, another with 22000 km listed for SAR 54000, and another with 20000 km listed for SAR 46000. These listings suggest a range but are generally higher than the selling price. Considering the car's mileage of 30000 km, which is between the sold car and the listed cars, and adjusting for the average condition, I estimate the market price to be slightly lower than the selling price due to the higher mileage.
