To estimate the price of the 2023 Changan CS85 I4 2.0L Turbo Charged Limited (Top) with 39000 km mileage, I first considered the selling prices of similar cars. A similar car with 3000 km sold for 79000 SAR, and another with 40000 km sold for 74800 SAR. A car with 15500 km sold for 80000 SAR, and one with 300 km in average condition sold for 82000 SAR. The car with 40000 km is closest in mileage to the target car and sold for 74800 SAR. The listed prices for similar cars range from 76000 SAR to 85000 SAR, with a car having 40000 km listed for 76000 SAR. Considering the selling prices and the listed prices, the market value for the target car with 39000 km is likely slightly below the 74800 SAR selling price due to higher mileage compared to the 3000 km car that sold for 79000 SAR. Therefore, I estimate the market price to be around 74000 SAR.
