To estimate the price of the 2020 Hyundai Kona I4 2.0L Smart 2.0L (Mid) with 59000 km mileage, I first considered the actual selling price of a similar car with 66000 km mileage sold for SAR 54500 on 2024-03-10. This is the most reliable data point. Next, I looked at the listed prices of similar cars. The closest match in terms of mileage and variant was listed for SAR 60000 but was delisted on 2024-05-22, indicating it might have been overpriced. Other listings ranged from SAR 32000 to SAR 70500, but these had varying mileages and conditions. The most relevant listings were around SAR 55000 to SAR 62000. Considering the selling price and the listed prices, I estimated the market price to be slightly lower than the average listed price but close to the actual selling price.
