2020 Mercedes-Benz GLC 300 AMG Line 4MATIC Auto 2.0L Petrol · RO70 AEE

The most recent MOT test on January 27, 2026, confirms this GLC 300 AMG Line is currently roadworthy with no defects recorded. The absence of advisories or failures across the last four tests—spanning from September 2023 to January 2026—indicates a stable maintenance trend. However, the duplicate entry for February 2024 (one pass, one fail at identical mileage) suggests either a retest or a potential administrative anomaly. No recurring faults appear in the record, though the lack of advisories does not preclude underlying issues such as degraded suspension bushes, coil spring fatigue, or subtle drivetrain wear common in high-performance AMG models at this mileage. The mileage progression shows consistent usage without abrupt spikes or prolonged inactivity. At 37,720 miles over six years, the average annual distance of 6,287 miles aligns with typical light-to-moderate usage for this class of vehicle. The gap between tests—ranging from 10 to 14 months—is standard, with no evidence of extended periods where maintenance may have been neglected. The absence of mileage jumps or extended storage periods reduces the likelihood of severe corrosion or fluid degradation, though a thorough inspection of fluid levels and condition remains prudent. Given the clean MOT history, priority should be given to inspecting high-wear components not directly tested under MOT regulations. The suspension—particularly the rear multi-link geometry and front strut mounts—should be scrutinised for excessive play or bush deterioration, as AMG models often experience accelerated wear in these areas. Brake calipers and binding mechanisms, while not flagged in tests, warrant visual inspection for corrosion or improper clearance, especially if the vehicle has been driven in wet conditions. Additionally, the 4MATIC drivetrain’s differential and transfer case should be checked for leaks or unusual noise, as these are not routinely covered in MOT tests but can develop issues at this mileage. Finally, the exhaust system’s structural integrity and catalytic converter efficiency should be verified, as emissions-related failures are not uncommon in high-performance vehicles.
