2008 Mazda 6 2.0L Petrol · DN08 RRO

The vehicle remains roadworthy, but the maintenance history reveals a persistent and worsening trend of corrosion and component degradation. While the most recent test in December 2025 at 65,006 miles passed, it flagged recurring structural issues regarding the sub-frame and suspension arms that have been present for several consecutive years. The exhaust system shows a clear progression, moving from heavy corrosion to an active minor leak, indicating that the metalwork is nearing a point of structural failure. At 65,006 miles, this eighteen-year-old Mazda has covered exceptionally low mileage, averaging approximately 3,600 miles per year. The data shows consistent annual usage with intervals of roughly 3,000 to 4,000 miles between tests from 2022 through to 2025. This low mileage often suggests less mechanical wear on the engine, but it also explains the high levels of corrosion observed, as vehicles that sit stationary are more frequently exposed to moisture without the drying effect of heat generated by regular use. A buyer must conduct a thorough physical inspection of the rear sub-frame and suspension arms, as the tester has repeatedly noted corrosion in these areas since at least 2022. Although these are currently classified as not seriously weakened, the persistence of these faults across all four arms suggests the underbody environment is harsh. Furthermore, the brake discs are consistently flagged as being pitted and scored across every inspection, which is a common symptom of low-mileage use where the discs are not kept clean. Specific attention should also be paid to the exhaust system, as the leak noted in the 2025 test follows a major leak that caused a failure in late 2024. The headlamp lenses are also chronically defective to near the legal limit, indicating UV damage or clouding that has not been addressed. Given the structural nature of the reported rust, the integrity of the chassis mounting points is the primary concern for long-term viability of this vehicle.
