2007 Mercedes C 2.1L Diesel · KT07 RVR

The latest MOT test conducted on 6 November 2025 resulted in a pass, though the vehicle history indicates a period of persistent, unresolved maintenance issues. While the car successfully cleared its most recent inspection, the recurring advisories regarding exhaust smoke and front brake disc condition suggest a pattern of deferred maintenance. The failure in November 2025 due to a faulty side repeater, combined with the repeated appearance of the same advisories over multiple years, indicates that the vehicle is being kept in a strictly roadworthy state rather than being proactively maintained to a high mechanical standard. With a recorded mileage of 48,025 miles over a 19-year lifespan, this Mercedes has covered an average of approximately 2,500 miles per annum. This extremely low usage profile is a double-edged sword for a vehicle of this age. While the drivetrain components have not been subjected to high-mileage wear, the car has likely spent significant periods stationary. Low-mileage vehicles frequently suffer from issues related to lack of use, such as the degradation of rubber components, the seizure of brake calipers, and the accumulation of moisture within the engine oil and fuel systems, which can lead to internal corrosion and the exhaust smoke noted in the MOT history. When inspecting the vehicle, you must investigate the source of the excessive exhaust smoke, which could indicate worn valve stem seals, turbocharger seal failure, or issues with the crankcase ventilation system, all of which are common in older, low-mileage engines. During your test drive, listen carefully for any juddering under braking, which would confirm the severity of the pitted front discs noted in the MOT. If the pedal feels spongy or the car pulls to one side during deceleration, this points to binding calipers or seized slider pins resulting from long periods of inactivity. You should also check the service history for evidence of time-based maintenance, such as brake fluid changes and coolant flushes, as these fluids degrade over time regardless of the distance covered. Given the consistent history of tyre perishing advisories, you must conduct a thorough physical inspection of all four tyre sidewalls for dry rot, cracking, or perishing, as these are critical safety failures that may not be fully captured by the MOT tester. Even if the tread depth remains legal, rubber that has hardened with age loses its structural integrity and grip. Furthermore, inspect the underside of the vehicle for signs of surface corrosion on the subframes and brake lines, which is typical for cars that have stood for long durations in damp conditions. Ensure the 12V battery holds a strong charge, as older batteries in low-use vehicles often fail unexpectedly, and verify that all electronic systems are functioning correctly, as the recurring lighting faults suggest potential issues with wiring or module corrosion.
