2007 Mazda 6 2.0L Petrol · YB07 CDY

The vehicle presents a concerning trend of progressive structural degradation despite maintaining a current roadworthy status. While it passed its most recent test in June 2025 at 123,924 miles, this followed a significant failure just three days prior. The failure in June 2025 revealed a critical structural issue regarding the offside rear suspension component mounting, affecting the outer sill and inner wheel arch. Although the subsequent pass noted these as not seriously weakened, the presence of deep corrosion indicates that the chassis is reaching a terminal stage of material fatigue. The mileage pattern remains consistent with the vehicle's 19-year age, averaging approximately 6,500 miles per year. Data shows a steady accumulation of roughly 2,000 miles between the June 2023 and 2024 tests, and another 1,900 miles between the 2024 and 2025 tests. This low annual usage suggests light travel, but it also means the car may have sat stationary for long periods, which often accelerates the oxidation process common on this generation of Mazda 6. A buyer must conduct a thorough physical inspection of the underbody, specifically targeting the rear sub-frame and suspension mounting points. The record shows recurring corrosion in these areas since 2023, which has moved from minor spring mounting rust to structural integrity concerns. The persistent binding of both rear brakes noted across three consecutive years suggests seized calipers or worn slider pins that require immediate attention to prevent premature disc wear. Given the history of rust on the sill and wheel arches, the long-term viability of the vehicle is highly questionable.
