I started by examining the selling prices of similar used cars. The 2023 Mazda 6 I4 2.5L S (Base) with 20000 km sold for 81000 SAR on 2024-09-20. This is a newer model with lower mileage, so the price is likely higher than the 2022 model. The 2020 Mazda 6 I4 2.5L Ignite (Top) with 134089 km sold for 72000 SAR on 2024-10-03, and the 2020 model with 138000 km sold for 69000 SAR on 2024-06-12. These are older models with higher mileage, so their prices are lower. The 2021 Mazda 6 I4 2.5L Turbocharged Ignite (Top) with 94000 km sold for 90500 SAR on 2023-10-26, but it has a turbocharged engine and is a higher variant, which justifies a higher price. The new car price for a 2025 Mazda 6 2.5L Core is 97175 SAR. Applying depreciation for two years (15% per year), the estimated value for a 2022 model would be around 70000 SAR. Considering the 2022 model's mileage of 69900 km and its base variant, I estimate the market price to be slightly higher than the older 2020 models but lower than the newer 2023 model, around 75000 SAR.
