2004 Mercedes C 2.7L Diesel · YW53 BNB

The vehicle is currently roadworthy, but the maintenance trend shows a clear shift toward mechanical and structural neglect. While it passed its most recent test in April 2026 at 199,068 miles, this followed a significant failure just weeks prior. The March 2026 failure revealed a cascade of defects including excessive brake pipe corrosion, suspension wear, and poor brake efficiency. Although these issues were addressed to secure the pass, the volume of faults suggests that the owner has only been reacting to MOT testing requirements rather than performing preventative maintenance. The mileage pattern is consistent with a 22-year-old vehicle, averaging approximately 9,000 miles per year. However, a notable spike in usage occurred between April 2024 and March 2026, where the car covered over 23,000 miles in just thirteen months. This rapid accumulation likely correlates with the onset of the mechanical wear seen in the subsequent tests. The high mileage of nearly 200,000 miles places significant strain on aging components, which is evidenced by the recurring failures in the braking-related hardware and the chassis. A buyer must conduct a thorough physical inspection of the braking system and chassis. The record shows persistent corrosion across all four brake pipes dating back to 2023, indicating a systemic issue with rust or a failure to clean and protect the metal lines. The rear sub-frame is flagged as corroded in two consecutive tests; while the tester deemed it not yet seriously weakened, structural rust on a high-mileage Mercedes is often a precursor to more serious failures. Specific attention is also required for the front-end suspension. The track rod ends, anti-roll bar bushes, and offside front suspension arm all appeared as failures or advisories in the early 2026 test. The minor exhaust leak and non-excessive oil leak suggest the vehicle is reaching a stage where multiple component failures will become frequent. Prospective buyers should verify that the repairs made after the March 2026 failure were executed to a professional standard rather than being temporary fixes.
