To estimate the price of the 2017 Hyundai Sonata I4 1.7L Turbocharged (Diesel) N-Line (Top++) with 291000 km mileage, I considered the following data points: 1) The listed price of a 2018 Hyundai Sonata I4 2.4L Supreme (Top) with 253000 km is SAR 39500. 2) The listed price of a 2019 Hyundai Sonata I4 2.0L Classic (Mid+) with 97000 km is SAR 58000. Given the higher mileage and older model year of the target car, I adjusted the price downwards. Additionally, the new car prices for 2025 models range from SAR 108485 to SAR 143100, indicating a significant depreciation over the years. Considering the car's age, mileage, and condition, I estimated the market price accordingly.
