To estimate the price of the 2021 Chery Tiggo7 Pro I4 1.5L Turbo Charged Pro Comfort (Base) with 104000 km mileage, I considered the following data points: 1. A similar car with the same variant and slightly lower mileage (97000 km) sold for SAR 37000 on 2024-04-04. 2. Another similar car with the same variant but higher mileage (130500 km) sold for SAR 39000 on 2024-07-10. 3. A similar car with the same variant and similar mileage (57000 km) sold for SAR 40000 on 2024-07-24. 4. The listed price for a similar car with the same variant and exact mileage (104000 km) is SAR 40000, but listed prices are generally higher than actual selling prices. Considering the car's condition is good, I adjusted the price slightly higher than the SAR 37000 sale but lower than the SAR 40000 listed price.
