To estimate the price of the 2023 Changan Eado I4 1.4L Turbo Charged Smart (Mid) with 117000 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, and the 2021 Changan Eado I4 1.6L Limited (Top) with 146000 km sold for 32500 SAR in May 2024. Considering the Smart (Mid) variant is typically cheaper than the Limited (Top) variant, I adjusted the price downwards. Next, I reviewed the listed prices of similar cars. The 2022 Changan Eado I4 1.4L Smart (Mid) with 145000 km was listed for 36500 SAR, and the 2021 Changan Eado I4 1.6L Smart (Mid) with 51000 km was listed for 37000 SAR. Given the higher mileage of the target car, I adjusted the price further down. Finally, I considered the new car price of the 2025 Changan Eado Smart (Mid) at 63756 SAR and applied depreciation logic. Combining all these factors, I arrived at the final estimate.
