2008 Mazda 6 2.0L Petrol · SH08 OGG

The vehicle remains roadworthy but the maintenance trend shows a clear progression towards escalating structural issues. While the most recent test in June 2025 at 143,930 miles passed, it highlighted corrosion on the nearside and offside rear vehicle structures. Although the tester noted that structural rigidity was not significantly reduced, this follows general underbody corrosion noted in 2021 and specific sill corrosion in 2024, indicating that rust is actively advancing. At 143,930 miles over 18 years, the Mazda has averaged approximately 8,000 miles per year, which aligns with typical usage for a car this age. There is a notable mileage gap of 4,788 miles between June 2021 and June 2022, followed by more consistent accumulation of roughly 2,600 to 4,800 miles per year in the subsequent tests. This consistent usage suggests the car is driven regularly, yet the low annual mileage does not protect the aging metal components from age-related degradation. A buyer must conduct a thorough physical inspection of the chassis to assess the extent of the rust on the rear structural points and sills. The history shows recurring suspension issues, including corroded coil springs on all corners flagged in 2024 and ball joint play that caused a failure in 2022. The transmission oil leak recorded in 2021 should be monitored to ensure it has not worsened into a significant leak. Given the previous failures for worn tyres and edge wear in 2024, the current condition of all four tyres also requires immediate attention.
