2010 Mazda 6 1.8L Petrol · NG59 MVA

The Mazda 6 shows a consistent pattern of progressive surface corrosion affecting the critical lower chassis and suspension components. In the most recent test in July 2025 at 130,731 miles, the vehicle passed despite advisories for the rear sub-frame and lower rear suspension arms. While these components were noted as not seriously weakened, they represent a recurring issue dating back to 2023 when the front suspension arms were also flagged. The 2024 inspection at 119,008 miles further identified wear in the rear suspension arm bushes and corrosion on both rear brake pipes, suggesting that the vehicle's underbody has been subject to significant environmental degradation. At 130,731 miles over 16 years, the car has averaged approximately 8,171 miles per year, which aligns with typical annual usage for its age. The MOT history indicates regular annual testing, with a single failure in June 2023 at 112,421 miles. That failure was caused by worn front tyres and thin brake pads, both of which were addressed before the subsequent successful pass three days later. The mileage gap between the 2024 and 2025 tests is roughly 11,000 miles, showing a consistent usage pattern without long periods of inactivity. A buyer should prioritize a thorough inspection of the structural integrity of the sub-frame and suspension arms, as the tester has repeatedly flagged corrosion in these areas across both the front and rear sections. The transition from surface rust to structural failure is a constant risk as the vehicle ages. Additionally, the previous mention of corroded rear brake pipes and worn suspension bushes in 2024 suggests that ongoing maintenance of the braking and handling systems is necessary. While the vehicle currently meets roadworthiness standards, the trend of rust on the chassis is the primary long-term concern for this specific example.
