To estimate the price of the 2015 Hyundai Sonata Supreme I4 2.4L with 108,000 km mileage, I focused on the selling prices of similar cars. The most relevant data point is a 2016 Hyundai Sonata Supreme with the same engine and condition, sold for 35,000 SAR in January 2024. Considering the one-year difference, I adjusted for depreciation. Another 2015 Supreme with higher mileage (169,500 km) sold for 30,000 SAR in June 2023. Given the lower mileage of the target car, I estimate a slightly higher value. A 2015 Classic variant with 187,000 km sold for 28,500 SAR in April 2024, indicating the Supreme variant's higher value. Considering these factors, I estimate the market price for the target car.
