2005 Mercedes C 5.4L Petrol · LN54 AEP

The vehicle currently holds a roadworthy status following a clean pass on 11 February 2026 at 90,574 miles. The overall maintenance trend appears stable, though the history reveals a pattern of immediate failures followed by successful passes. In both 2025 and 2026, the car failed the test just days before a successful result, suggesting that minor defects are addressed only when prompted by the MOT deadline rather than as part of proactive preventative maintenance. The mileage profile is notably low for a 21-year-old vehicle, averaging approximately 4,300 miles per year. Data from January 2024 at 87,929 miles to February 2026 at 90,574 miles shows an accumulation of only 2,645 miles over two years. While this low usage typically reduces wear on the drivetrain and engine, long periods of inactivity can lead to degradation of rubber components, perished seals, and fluid breakdown, which are not reflected in the odometer alone. A buyer should prioritise inspecting the structural integrity of the chassis and subframe points, as older Mercedes-Benz models are prone to corrosion that may remain hidden under road film. Given the low mileage, the inspector must also check for seized brake calipers or perished suspension bushes which often result from age and infrequent use. The recent failures indicate that the vehicle requires constant attention to remain compliant, so a thorough physical check of the components rectified prior to the previous February tests is essential.
