To estimate the price of the 2021 Changan CS95 I4 2.0L Turbo Charged Royal (Top) with 141000 km mileage in average condition, I first looked at the selling prices of similar cars. The most relevant data points are: a car with 144000 km in good condition sold for 70000 SAR on 2023-10-29, a car with 118000 km in average condition sold for 53000 SAR on 2024-02-01, and a car with 105000 km in average condition sold for 38000 SAR on 2024-07-03. Given the target car's mileage and condition, it is closer to the second and third data points. The listed prices of similar cars range from 40000 SAR to 75000 SAR, with the most relevant being 57000 SAR for a car with the same mileage and 65000 SAR for a car with slightly lower mileage. Considering the depreciation and the condition, I estimate the market price to be slightly lower than the average of the selling prices and listed prices for similar cars.
