To estimate the price of the 2020 Mazda CX-9 I4 2.5L Turbo Charged High+ Premium with 187,500 km mileage, I first considered the selling prices of similar cars. A similar variant with 146,000 km sold for 89,000 SAR on 2024-04-30, and another with 93,000 km sold for 110,000 SAR on 2024-04-23. A car with 95,236 km sold for 97,500 SAR on 2024-09-03. These prices suggest a decrease in value with higher mileage. The car in question has significantly higher mileage, which typically reduces the price. I also noted a similar car listed for 86,000 SAR with 180,000 km, which was delisted on 2024-06-27, indicating it might have sold for less. Considering these factors, I adjusted the price downward to account for the higher mileage and average condition.
