2021 Mercedes-Benz GLS600 Mybch 1ST Clss Mhev 4MA 4.0L Hybrid electric (clean) · LG71 RXH

This Mercedes-Benz GLS600 has maintained a clean MOT history with no defects recorded in either of the two most recent tests, both passing on their respective dates in September 2024 and September 2025. The most recent inspection, conducted just ten months ago at 5,104 miles, confirms the vehicle remains roadworthy under current DVSA standards. There is no evidence of recurring mechanical failures or advisory notes in the available record, suggesting the tester did not identify any latent issues requiring further attention. However, the absence of defects does not preclude the need for a thorough independent inspection, particularly given the vehicle’s low mileage and hybrid-electric powertrain complexity. The recorded mileage of 5,104 miles over five years—approximately 1,021 miles annually—indicates exceptionally light usage, which could imply long periods of storage or infrequent driving. The gap between tests aligns precisely with the annual MOT cycle, with no intermediate mileage recorded, which might suggest the vehicle was either not driven regularly or its maintenance was meticulously timed. While low mileage generally correlates with reduced wear on high-stress components like brakes, suspension, or drivetrain, the lack of intermediate service records means there is no confirmation of routine maintenance such as fluid changes, tyre rotations, or hybrid battery health checks. This pattern raises questions about whether basic servicing was consistently performed, even if the MOT tests passed without issue. Given the clean MOT record but low mileage, a buyer should prioritise an inspection of the hybrid battery system, particularly the high-voltage components and cooling circuits, as these are not routinely covered by MOT testing. The suspension system—including coil springs, bushes, and dampers—should be examined for uneven wear or corrosion, especially if the vehicle has spent extended periods stationary. Brake systems, while not flagged in the MOT, warrant scrutiny for binding calipers, uneven disc thickness, or corrosion on the rear axles, which are common in low-mileage vehicles exposed to moisture. Additionally, the underbody and wheel arches should be inspected for corrosion, as prolonged inactivity can accelerate rust development in critical structural areas. The tyres, though not mentioned in the MOT, should be checked for uneven wear patterns, which could indicate alignment issues or improper storage.
