2020 Mercedes-Benz GLC 1.9L Diesel · LR70 PJO

The most recent DVSA MOT test for this 2020 Mercedes-Benz GLC was conducted on 30 October 2025 and resulted in a pass with no defects or advisories recorded, indicating that at the point of examination the vehicle met all statutory roadworthiness requirements. This clean outcome, when viewed alongside the previous pass from 29 October 2024, demonstrates a stable and well-maintained trend over the most recent testing cycle. However, it should be noted that the pass on 29 October 2024 was issued immediately after a failed test on the same date, where the vehicle was presented with three dangerous tyres. The fact that a pass was subsequently issued on the same day suggests the tyres were replaced prior to re-examination, which is a positive indicator of responsive maintenance, though it does highlight that tyre condition had been allowed to deteriorate to a dangerous threshold. With 59,219 miles recorded over approximately six years, this GLC has covered around 9,870 miles annually, which sits comfortably within the typical range for a vehicle of its age and class. There is no evidence in the MOT history of extended standing periods or unusually rapid mileage accumulation, both of which can introduce their own mechanical concerns. The current annualised figure is consistent with regular mixed-use driving, which generally supports healthier component longevity across the braking system, drivetrain, and suspension, as frequent short cycles and prolonged inactivity can both accelerate specific wear patterns. Despite the clean MOT history, prospective buyers should still conduct age and mileage-appropriate physical inspections. Tyres on a six-year-old vehicle can suffer sidewall perishing and cracking from natural rubber degradation even when tread depth remains adequate, so all four tyres should be examined for signs of crazing, bulges, or uneven wear patterns, particularly on the driven axle. Although there is no evidence of prolonged standing, the brake discs and calipers should be inspected for surface corrosion or evidence of seizing, as binding calipers can develop from infrequent use and may produce pulling under braking or uneven pad wear. A road test should include firm braking from higher speeds to detect any brake shudder, which would indicate disc warping, and slow-speed manoeuvres over uneven surfaces to identify any suspension knocks or clonks that may point to worn bushes or coil springs. Further buyer due diligence should include verification of time-based servicing items that fall outside the scope of an MOT test. Brake fluid should ideally have been renewed within the last two to three years regardless of mileage, as hygroscopic absorption of moisture degrades its boiling point and can compromise safety under heavy braking. Similarly, coolant, transmission fluid, and the condition of the 12V battery warrant checking, as Mercedes-Benz vehicles of this era are sensitive to voltage irregularities and may display warning messages if battery health is compromised. It is advisable to request a full service history, ideally with main dealer or specialist stamps, and to confirm that all recommended Mercedes-Benz maintenance schedules have been observed. A pre-purchase inspection by an independent Mercedes specialist would be highly recommended to assess the air suspension system, if fitted, as well as the condition of the timing chain and engine ancillaries, which are critical service items on this model.
