2012 Mercedes-Benz C 3.0L Diesel · MY12 MJC

The vehicle is currently roadworthy, but the maintenance trend shows a clear shift towards developing corrosion and braking system neglect. While it passed its most recent test in May 2026 at 102,857 miles, the tester flagged multiple significant advisories that were not present in previous years. The appearance of corrosion on the rear coil springs, anti-roll bar, and the rear sub-frame indicates that the vehicle is beginning to suffer from environmental degradation, despite the relatively low mileage. The mileage pattern is consistent with a vehicle used for modest annual distances, averaging approximately 7,300 miles per year. There is a notable gap of 14,126 miles between April 2024 and April 2025, followed by another 14,265-mile interval leading up to the most recent test in May 2026. This steady accumulation suggests regular use, yet the jump from a clean record in 2023 to multiple mechanical defects in 2026 suggests that wear and tear issues have accelerated in recent years. A buyer must prioritize a thorough inspection of the braking system and underbody. The record shows a persistent issue with imbalanced front brakes that only marginally met requirements in both 2024 and 2025, coupled with a handbrake performing at the absolute limit of 17%. The recurring mention of corroded brake pipes, which were noted in 2022 and again in the most recent test, suggests a lack of preventative maintenance regarding fluid lines. Furthermore, the structural integrity of the sub-frame and suspension springs requires close monitoring, as the noted corrosion is not yet a failure but is likely to lead to future failures if not addressed. The nearside front tyre being worn to the legal limit also indicates that basic consumable upkeep is being overlooked.
