To estimate the price of the 2023 Chery Tiggo4 Pro I4 1.5L Comfort (Base) with 20000 km mileage, I considered the listed price of a similar 2023 Chery Tiggo4 I4 1.5L Standard variant with 42002 km mileage, which is SAR 48000. Given that the target car has lower mileage and is a Comfort variant, which is typically higher than the Standard variant, I adjusted the price upwards. Additionally, the condition of the car is average, which might slightly lower the price. Factoring in these aspects, I arrived at the final estimate.
