2020 Mercedes-Benz GLC 300 AMG Line DE 4MATIC A 1.9L Electric diesel · RO70 RBX

The latest MOT test conducted on 30 August 2025 resulted in a pass, and the overall maintenance trend for this vehicle appears exceptionally stable. The history shows a consistent record of passing inspections without any listed defects or advisories since 2023. While a failure was recorded on 29 August 2025, the immediate pass the following day and the absence of recorded defects suggest a minor administrative or trivial issue that was rectified instantly, rather than a systemic mechanical failure or a recurring fault. The vehicle has covered 70,523 miles over approximately six years, averaging roughly 11,754 miles per annum. This represents typical usage for a premium SUV of this specification, suggesting a balanced duty cycle of mixed urban and motorway driving. This level of usage is generally preferable to very low mileage, as it prevents the stagnation of rubber seals and avoids the binding of brake calipers, although it indicates that various wear-and-tear consumables are now entering a phase where replacement may be required. As the MOT history is remarkably clean with no advisories, the buyer should focus on age-related degradation and comprehensive service verification. It is essential to scrutinize the service records to ensure that engine oil, filters, and transmission fluids have been changed according to the manufacturer's intervals, as calendar-based fluid degradation occurs regardless of MOT outcomes. Particular attention should be paid to the tyres; inspect the sidewalls for perishing or fine cracking and ensure the tread depth is consistent across the axle to rule out misalignment or worn suspension bushes. During the test drive, listen for any clunks from the suspension over uneven surfaces, which could indicate the onset of wear in the coil springs or bushings. Given the hybrid nature of the DE model, verify the health of the 12V auxiliary battery and ensure there is a smooth transition between electric and combustion power without undue hesitation. Finally, inspect the brake discs for surface corrosion or lip formation and ensure the brake pedal feel is firm without any shudder, confirming that the calipers are operating freely and the discs remain within acceptable tolerances.
