To estimate the price of the 2023 Hyundai Sonata I4 2.5L GDi Smart (Mid) with 87760 km mileage, I first looked at the selling price of a similar car: a 2023 Hyundai Sonata I4 2.5L Smart (Mid) with 13000 km sold for SAR 94500 on 2024-07-20. Given the higher mileage of the target car, I adjusted the price downwards. Next, I considered the listed prices of similar cars. A 2023 Hyundai Sonata I4 2.5L Smart (Mid) with 26000 km was listed for SAR 91000 and another with 13000 km was listed for SAR 94500. These listings suggest a price range but are higher due to lower mileage. I also noted a 2022 Hyundai Sonata I4 2.5L Smart (Mid) with 64000 km listed for SAR 77500, which is closer in mileage but a year older. Considering the depreciation and the higher mileage of the target car, I estimated the price to be slightly lower than the recent selling price of a similar car with lower mileage.
