To estimate the price of the 2021 Hyundai Sonata I4 2.5L Turbocharged N-Line (Top++), I considered the following data points: 1) A 2020 Hyundai Sonata I4 2.5L Classic (Mid+) with 140000 km sold for 63000 SAR on 2023-10-20. 2) A 2019 Hyundai Sonata I4 2.4L Smart (Mid) with 78000 km sold for 62500 SAR on 2023-11-01. 3) A 2020 Hyundai Sonata I4 2.5L Smart (Mid) with 115000 km sold for 58500 SAR on 2023-11-22. 4) A 2020 Hyundai Sonata I4 2.4L Standard with 127900 km sold for 57000 SAR on 2024-01-01. 5) A 2020 Hyundai Sonata I4 2.5L Standard with 105000 km sold for 57000 SAR on 2024-02-25. 6) A 2020 Hyundai Sonata I4 2.5L Standard with 182308 km sold for 47000 SAR on 2024-03-17. 7) A 2020 Hyundai Sonata I4 2.5L Smart (Mid) with 126000 km sold for 49500 SAR on 2024-06-25. 8) A 2023 Hyundai Sonata I4 2.5L Smart (Mid) with 13000 km sold for 94500 SAR on 2024-07-20. Additionally, a 2021 Hyundai Sonata N-Line I4 2.5L with 40001 km was listed for 123000 SAR but delisted on 2023-12-29. Considering the higher trim (N-Line) and lower mileage (74644 km) of the target car, I adjusted the price upwards from the average selling prices of similar cars, while also factoring in the depreciation and the higher listing price of a similar car.
