2018 Mercedes-Benz GLC 2.1L Diesel · CA17 THG

The vehicle’s most recent MOT test on 10 April 2026 at 61,237 miles confirms current roadworthiness with no defects recorded, indicating a stable maintenance trend over the past year. The absence of advisories or recurring failures in the last three tests suggests the vehicle has been kept in sound mechanical condition, though the 2023 near-side rear tyre issue—flagged for wear close to the legal limit—was an isolated incident resolved before the next test. No evidence of worsening structural or drivetrain concerns is present, though the lack of advisories in recent years does not preclude hidden wear on components like suspension bushes or coil springs, which are not routinely inspected under MOT regulations. The mileage progression shows consistent usage, averaging around 7,655 miles annually, which aligns with typical wear patterns for a vehicle of this age. The most notable gap is between the 2022 and 2023 tests, where mileage jumped from 34,954 to 40,234—a 5,280-mile increase in under a year—before settling into a steadier pace. This spike could imply either intensive driving or a period of under-maintenance, though the subsequent tests show no immediate consequences. The most recent test, just three months ago, means the vehicle remains within the current MOT validity period, but buyers should verify if any non-MOT-related services (e.g., fluid changes, timing belt inspections) have been neglected. Given the clean MOT history, priority should be given to inspecting high-wear items not covered by the test, such as the suspension’s front and rear bushes for cracking or excessive play, and the coil springs for corrosion or fatigue—common issues in Mercedes-Benz models of this era. The brakes, while not flagged, should be checked for uneven pad wear or binding calipers, particularly on the near-side rear where the 2023 tyre issue suggests potential cornering stress. Structural integrity remains a concern; examine the wheel arches, sills, and subframe for signs of rust penetration or weld repairs, as these are often overlooked but critical to long-term safety. The absence of advisories does not rule out hidden corrosion or drivetrain wear, so a thorough inspection of the exhaust system for leaks or catalytic converter efficiency is advisable.
