2006 Mazda 6 1.8L Petrol · KD06 TFF

Structural corrosion on the sills and recurring issues with braking components and lighting define the mechanical profile of this vehicle, which passed its most recent MOT on 22 October 2025. While the latest result is a pass, the record shows a trend of progressive deterioration, particularly regarding the vehicle's chassis integrity and consumable wear. The presence of corrosion on both nearside and offside sills within 30cm of a mounting, alongside previous advisories for corroded underseals, indicates an ongoing issue with oxidation on the vehicle's lower structure. The recorded mileage of 104,028 miles over approximately twenty years represents a low annual average of roughly 5,201 miles. This usage pattern suggests the vehicle has been driven infrequently, which can often lead to specific mechanical vulnerabilities. While lower mileage typically implies less wear on the drivetrain, it can also result in components such as seals, suspension bushes, and braking systems being subject to more environmental degradation or seizing due to periods of inactivity rather than mechanical fatigue from high-speed motorway use. Prospective buyers should pay close attention to the chassis and suspension during a physical inspection and test drive. The advisory for sill corrosion and previous reports of underseal degradation necessitate a thorough check for structural integrity; look for bubbling paint or visible scale on the sills and mounting points. Regarding the suspension, the history of corroded coil springs and worn anti-roll bar linkage ball joint dust covers suggests that the vehicle may exhibit knocking or clunking sounds when traversing uneven surfaces or speed bumps. Any rhythmic thudding or loose feeling through the steering could indicate that these suspension components require replacement. The braking system has been a recurring point of failure and advisory, with recent notes regarding worn rear brake discs and previous dangerous failures involving thin front brake pads. During a test drive, it is essential to monitor for any pedal judder, which could indicate warped or heavily worn discs, or a pulling sensation to one side under braking. Additionally, the advisory regarding a worn drive belt and clouded headlamp lenses suggests that peripheral maintenance is required. Check for any squealing from the engine bay upon startup and ensure the light output is sufficient for night driving, as the lenses appear to have surface degradation.
