To estimate the price of the 2022 Mazda 6 I4 2.5L Ignite (Top) with 100000 km mileage, I first looked at the selling prices of similar cars. A 2021 Mazda 6 I4 2.5L Turbocharged Ignite (Top) with 94000 km sold for 90500 SAR on 2023-10-26. Considering the 2022 model is newer but has higher mileage, the price should be slightly higher but adjusted for the additional mileage. Another 2020 Mazda 6 I4 2.5L Ignite (Top) with 138000 km sold for 69000 SAR on 2024-06-12. This car is older and has higher mileage, so the 2022 model should be priced higher. The new car price for a 2024 Mazda 6 2.5T Ignite is 126500 SAR. Applying a 10% annual depreciation for two years, the estimated value for a 2022 model would be around 102850 SAR. However, considering the actual selling prices and the listed price of a similar 2022 model at 117500 SAR, the market price should be adjusted accordingly. The listed price of 93000 SAR for a 2022 model with lower mileage also provides a reference point. Balancing these factors, the estimated market price is derived.
