2014 Mercedes-Benz C 2.1L Diesel · RAB 66

The overall roadworthiness trend is exceptionally stable. The most recent test on 10 September 2025 at 82,443 miles, conducted less than nine months ago, resulted in a clean pass with zero defects or advisories recorded. This flawless record extends unbroken through the previous four consecutive annual tests, demonstrating a consistently high maintenance baseline where no mechanical or structural faults have ever escalated to a failure point. Mileage accumulation aligns with typical use for a twelve-year-old executive car. Between the September 2021 test at 61,963 miles and the September 2025 test at 82,443 miles, the vehicle covered roughly 20,480 miles over four years. This breaks down to a steady annual increase of approximately 5,000 to 5,500 miles, which sits slightly below the lifetime average of 6,870 miles per year. The testing schedule shows no gaps, and the mileage graph shows no sudden spikes, ruling out periods of harsh heavy use or prolonged standing that might invite drivetrain neglect or moisture-related corrosion. Despite this pristine MOT record, a buyer must not assume every component is freshly serviced. The complete absence of advisories across five years suggests the tester never flagged items approaching their wear limits, which sometimes indicates a vehicle receiving regular pre-test replacements, but can also mean consumables are now quietly reaching their end of life without triggering official warnings. A physical inspection should therefore focus on tyre tread depths across all four corners, brake disc thickness and pad material, and the condition of suspension bushes and coil springs. Mercedes-Benz C-Class models of this era are known for rear suspension bush degradation and occasional binding brake calipers, so a close check of the rear subframe bushes and brake disc edges for rust lips is essential to verify the true mechanical condition beneath the paper-perfect history.
