2006 Mazda 6 2.0L Petrol · HY06 WHB

A persistent theme of corrosion and minor oil leakage runs through the MOT history, with every test from 2021 to 2025 recording advisories for an oil leak, brake‑pipe rust and body‑structure corrosion, while suspension mounting areas are repeatedly flagged as corroded. The pattern is punctuated by occasional failures – notably the off‑side front tyre bulge in 2021, a missing steering‑rack gaiter in 2023 and a series of paired fail/pass entries on the same day in October 2025, indicating that remedial work was carried out just in time to achieve a pass. The cumulative picture is one of ongoing, low‑level deterioration rather than isolated faults. At 174,830 mi the car averages roughly 8,700 mi per year, a mileage rate that sits comfortably within normal usage for a twenty‑year‑old model. The MOT record shows no gaps in annual testing, suggesting the odometer reading has been consistently logged. Such mileage will have naturally advanced wear on consumables – brake pads, tyre tread, bushings and engine seals – and will have contributed to the progressive corrosion observed on the chassis and suspension mounting points. When inspecting, watch for any fresh oil drips beneath the engine bay and for oil staining around the valve‑cover gasket or on the spark‑plug wells, as the recurring advisory points to a leak that, while not excessive, could worsen. Examine the brake‑pipe for surface rust, pitting or any signs of fluid seepage; a softened pedal or a faint brake‑fluid smell may indicate that the corrosion has compromised the pipe’s integrity and could require replacement. The body‑structure advisories focus on the inner and outer sills; a visual check for flaking paint, bubbling rust or deep pitting in these areas will reveal whether the structural rigidity remains acceptable. Given the historic rear‑suspension and sub‑frame corrosion, feel for any clunk or looseness when the car is driven over bumps and listen for metallic noises that could signal deteriorated mounting points. Verify that the rear tyres are free of bulges, especially on the side that previously failed, and confirm that tread depth meets legal limits across both edges. Finally, test the steering for any play or uneven feedback that might arise from the missing front‑rack gaiter, and inspect the rack boots for cracks or ingress of dirt. A thorough visual and road‑test inspection of these specific items will be essential before committing to purchase.
