2014 Mercedes-Benz C 2.1L Diesel · SM14 RTY

The vehicle is currently roadworthy but the maintenance history reveals a pattern of reactive rather than proactive mechanical care. While the most recent test in September 2025 at 120,679 miles was a pass, it noted a persistent oil leak and thinning rear brake pads. The trend shows a temporary improvement following a major failure in late 2024, yet the recurring nature of mechanical-related issues suggests that the owner typically only addresses faults once they reach the point of an MOT failure. At 120,679 miles over 12 years, this Mercedes-Benz averages approximately 10,000 miles per year, which is entirely consistent with typical UK road-use patterns. The mileage data shows steady progression, with roughly 11,000 miles covered between the September 2023 and 2024 tests, and another 11,000 miles recorded by September 2025. This consistent accumulation indicates the vehicle has not sat stationary for long periods, but it subjects subjects components to standard wear on rubber components and braking assemblies. A physical inspection must focus heavily on the suspension and braking systems, as these have shown repeated failures. The 2023 failure highlighted excessively worn front suspension arm bushes, while the 2024 test identified a binding offside rear service brake and a fractured inner rim on the wheel. You should inspect all suspension bushings for further tearing and verify that the brake calipers are not sticking, which caused the binding noted previously. The 2024 failure regarding exhaust emissions and an engine malfunction light also suggests potential engine management issues that should be checked via diagnostics to ensure they were fully rectified. The persistent oil leak noted in both 2024 and 2025 requires a close look to determine if it is a minor gasket leak or a more significant seal failure. Given the history of structural tyre damage and fractured wheel rims in 2024, the buyer should also inspect the current tyres and wheels for signs of impact damage or uneven wear. The vehicle shows a history of neglecting basic consumables until they become unsafe, necessitating a thorough check of the undercarriage for corrosion and general mechanical integrity before purchase.
