To estimate the price of the 2018 Changan CS75 Turbo Charged I4 1.8L Plus Limited (Top) with 213,000 km mileage and average condition, I first considered the selling prices of similar cars. A 2020 model with the same variant and average condition sold for 46,000 SAR with 131,000 km on 28 July 2024. A 2019 model with the same variant sold for 31,500 SAR with 170,000 km on 1 April 2024. A 2017 model with the same variant and average condition sold for 28,000 SAR with 192,000 km on 23 December 2023. These prices suggest a depreciation trend. The 2018 model listed for 33,000 SAR with 229,000 km was delisted on 6 July 2024, indicating a likely lower selling price. Considering the mileage and condition, I estimate the market price to be slightly lower than the 2019 model's selling price, accounting for the additional mileage and age.
