To estimate the price of the 2017 Hyundai Sonata I4 2.4L Smart (Mid) with 205500 km mileage and average condition, I focused on similar cars with the same variant and condition. The most relevant data point is a 2017 Sonata Smart (Mid) with 298000 km sold for 32500 SAR in November 2023. Considering the lower mileage of the target car, it should be valued higher. A 2016 Smart (Mid) with 138000 km sold for 32000 SAR in March 2024, and a 2018 Smart (Mid) with 125000 km sold for 32000 SAR in June 2024. These suggest a depreciation trend. Given the target car's mileage and condition, I estimate its value slightly above the 2017 model with higher mileage but below the 2018 model with lower mileage, around 34000 SAR.
