2020 Mercedes-Benz GLC 300 AMG Line Prem+ E 4M A 2.0L Hybrid electric · LL70 FPZ

The most recent MOT test conducted in December 2025 resulted in a pass, with a single advisory noted regarding a nail in the nearside rear tyre. When evaluating the overall maintenance trend, there is a clear trajectory of improvement following a significant failure in early 2024. That specific failure was critical, involving dangerous defects where tyre cords were exposed, indicating a period of neglected consumable maintenance. However, the subsequent clean pass in late 2024 and the minimal advisory in 2025 suggest that the vehicle's upkeep has stabilised and is currently being managed more effectively. The recorded mileage of 29,640 miles over a six-year period represents an annual usage rate of approximately 4,940 miles, which is considerably lower than the UK average. While this low mileage implies reduced mechanical wear on the engine, drivetrain, and suspension components, it necessitates a different inspection approach. Vehicles that are driven infrequently can suffer from the effects of prolonged periods of standing, which can lead to fluid degradation, seal drying, and the accumulation of moisture within various systems. Due to the documented history of tyre-related defects, a meticulous inspection of the wheel assemblies is required. You should check all tyres for uneven tread wear, particularly on the edges, as this can be a symptom of incorrect wheel alignment or worn suspension bushes. During a test drive, pay close attention to any vibrations through the steering wheel or seat, which could indicate structural tyre damage or unaddressed issues from previous impacts. Ensure that the tyres are not only within legal tread limits but also show no signs of bulging or irregular profiles that could indicate internal cord damage. Furthermore, the low-usage profile of this Mercedes-Benz requires specific attention to age-related degradation. Inspect the brake discs for heavy surface corrosion or pitting, which often occurs when a vehicle is not driven regularly, and listen for any signs of binding calipers or brake shudder. Check the tyre sidewalls for perishing or fine cracking, as rubber degrades over time regardless of mileage. It is also essential to verify the service history for time-based maintenance, such as annual oil changes and brake fluid flushes, to ensure that fluids have not become contaminated by moisture. Finally, assess the 12V battery health, as low-mileage vehicles are frequently subject to discharge issues.
