2006 Mercedes-Benz C 1.8L Petrol · PW02 TAT

The vehicle shows a worsening maintenance trend regarding structural integrity and consumable wear. While the October 2024 test at 107,216 miles was clean, the most recent inspection on October 21, 2025, at 118,955 miles flagged significant concerns. The tester identified corrosion on the central rear sub-frame, which, while not yet seriously weakened, indicates an ongoing progression of oxidation. This follows a pattern of recurring issues with tyres and suspension components throughout the vehicle's life. The mileage profile suggests low annual usage, averaging roughly 5,948 miles per year over its twenty-year lifespan. This gradual accumulation is evident in the steady climb from 43,114 miles in 2014 to 118,955 miles in 2025. Such low usage can often lead to age-related degradation, such as the rubber deterioration seen in the October 2023 failure regarding the anti-roll bar linkage ball joint dust cover. The consistency of the annual testing intervals suggests a regular inspection regime, though the nature of the defects indicates that maintenance often reacts to failures rather than preventing them. A prospective buyer must prioritise a thorough inspection of the underside to assess the extent of the sub-frame corrosion. The history shows a recurring struggle with suspension geometry and component wear, specifically with ball joints and control arms, as seen in the October 2023 failure at 97,668 miles. The October 2025 report also highlighted multiple tyres worn close to the legal limit or on the edges, suggesting potential alignment issues or neglected tyre replacement cycles. The brake system also requires attention. The 2019 record noted lipped front brake discs, and while no specific brake failures appear in the most recent test, the history of consumable wear suggests checking the remaining thickness of discs and pads. Given the age and the specific mention of sub-frame corrosion, a professional inspection of all mounting points and structural metalwork is essential to ensure the vehicle remains safe for continued use.
