To estimate the price of the 2019 Haval H6 I4 2.0L Turbocharged Supreme (Top) with 90000 km mileage, I primarily considered the selling prices of similar cars. The most relevant data points are: 1) A 2019 Haval H6 Supreme with 137000 km sold for 37000 SAR on 2024-01-08, 2) A 2019 Haval H6 Supreme with 121000 km sold for 38500 SAR on 2024-07-20, and 3) A 2020 Haval H6 Supreme with 94000 km sold for 47000 SAR on 2024-07-29. Given the target car's lower mileage and good condition, it should be valued higher than the first two examples but slightly lower than the 2020 model due to the model year difference. The listed prices of similar cars range from 39000 to 49500 SAR, but these are generally higher than actual selling prices. Considering all these factors, I estimated the market price accordingly.
