2015 Mercedes-Benz C 2.1L Diesel · RX15 TDO

The vehicle is currently roadworthy, but the maintenance history reveals a worsening trend regarding deferred consumable repairs. While it passed its most recent test in March 2026 at 92,576 miles, it failed just one day prior due to a multitude of critical defects. The transition from a total failure to a pass indicates that the owner addressed only the immediate legal requirements to secure a certificate rather than following a proactive maintenance schedule for the vehicle's braking and suspension components. At 92,576 miles, this eleven-year-old Mercedes has averaged approximately 8,400 miles per year, which is consistent with typical UK usage patterns for its age. However, the data shows a significant spike in activity between March 2024 and March 2026, where the vehicle covered over 11,800 miles in just two years. This recent accumulation of mileage, combined with the repeated failures for tyre tread depth below legal limits, suggests the car is being driven frequently with minimal attention to preventative upkeep until the annual inspection threshold. A buyer must conduct a thorough physical inspection of the braking and suspension systems. The March 2026 record flagged pitting and scoring across all four brake discs and thin rear linings, indicating the braking system is reaching the end of its service life across the board. Furthermore, the presence of play in the nearside front lower suspension arm ball joint suggests that steering components are beginning to degrade, which can lead to uneven tyre wear and handling instability if not replaced. The recurring failures for tyres with insufficient tread in both 2024 and 2026 highlight a pattern of neglecting basic safety consumables. The buyer should verify that all four tyres are recently replaced and check for consistent wear, as the previous owner allowed them to reach the legal limit. Given the age of the vehicle and the noted mechanical wear, an inspection should also check for corrosion on the underbody and exhaust system, though no structural issues were specifically flagged in the provided history.
