The selling price of a 2021 Mazda 6 I4 2.5L Turbocharged, Ignite variant, with 94000 km mileage, sold for SAR 90500 on 2023-10-26. This car is a higher trim and older model with higher mileage. 2. The new car price for the 2024 Mazda 6 2.5L Core is SAR 97175. 3. The listed prices for similar 2023 Mazda 6 I4 2.5L Core (Base+) cars with similar mileage are SAR 91500 and SAR 100000.
