To estimate the price of the 2023 Changan Eado I4 1.4L Turbo charged Limited (Top) with 40000 km mileage, I first looked at the selling prices of similar cars. The 2022 Changan Eado I4 1.4L Limited (Top) with 92000 km sold for 39000 SAR in December 2023. Given the higher mileage and older model, this car would be valued lower than the 2023 model. The 2021 Changan Eado I4 1.6L Limited (Top) with 146000 km sold for 32500 SAR in May 2024, which is significantly older and has much higher mileage. The 2021 Changan Eado I4 1.6L Trend (Base) with 80000 km sold for 35500 SAR in August 2023, but it is a base variant and older. For new car prices, the 2024 Changan Eado Limited (Top) starts at 73876 SAR. Considering depreciation, the 2023 model would be around 66488 SAR (10% depreciation). Listed prices for similar 2023 models range from 40000 to 62000 SAR, but these are asking prices and not actual selling prices. Given the condition and mileage of the car in question, I estimate its market price to be slightly lower than the average of the listed prices but higher than the older sold cars.
