To estimate the price of the 2024 Changan CS95 I4 2.0L Turbocharged Royal (Top) with 18900 km mileage, I primarily considered the selling prices of similar cars. The most relevant data points are: 2023 Changan CS95 Royal (Top) with 10000 km sold for 93000 SAR on 2023-11-25, 2023 Changan CS95 Royal (Top) with 6300 km sold for 88000 SAR on 2024-01-08, and 2023 Changan CS95 Royal (Top) with 27000 km sold for 99500 SAR on 2024-07-21. These cars are similar in variant and condition. The 2024 model listed for 118500 SAR is likely overpriced as it hasn't been delisted. Considering the depreciation and the mileage, I adjusted the price slightly lower than the highest recent sale but higher than older sales due to the newer model year and lower mileage.
