To estimate the price of the 2019 Kia Sportage GT Line I4 1.6L Turbocharged EX 4WD (Top) with 84000 km mileage, I considered the following data points: 1. A 2019 Kia Sportage I4 1.6L EX (Mid) with 44000 km sold for 80500 SAR on 2023-10-06. 2. A 2019 Kia Sportage I4 2.4L EX (Mid) with 99000 km sold for 55000 SAR on 2023-11-25. 3. A 2019 Kia Sportage I4 1.6L EX (Mid) with 129000 km sold for 53000 SAR on 2023-12-09. 4. A 2019 Kia Sportage I4 1.6L EX (Mid) with 66000 km sold for 72000 SAR on 2024-01-05. 5. A 2019 Kia Sportage I4 2.0L EX (Mid) with 71500 km sold for 61000 SAR on 2024-04-23. 6. A 2020 Kia Sportage I4 1.6L EX 4WD (Top) with 35000 km sold for 70500 SAR on 2024-03-29. The target car is a higher trim (GT Line) and has a turbocharged engine, which generally commands a higher price. Considering the mileage and condition, I adjusted the price upwards from the mid-variant prices. The closest comparable is the 2020 EX 4WD (Top) with 35000 km sold for 70500 SAR, but adjusting for the higher mileage and the fact that it's a 2019 model, I estimated the price accordingly.
