2017 Mercedes-Benz GLC 3.0L Diesel · RE13 ADY

The vehicle’s most recent MOT test on 4 April 2025, at 38,091 miles, confirms it remains roadworthy with no defects recorded. This marks a consistent pattern of clean passes over the past three annual tests, with no advisories or failures since January 2022. The absence of recurring faults suggests the vehicle has been maintained at a basic level, though the lack of defects does not preclude hidden wear—particularly in high-stress areas like suspension bushes, coil springs, or brake components, which are not always tested comprehensively during an MOT. The most recent test’s proximity to today (just over three years ago) is acceptable, though the next due date (April 2028) will soon arrive, requiring renewed scrutiny. The recorded mileage of 38,091 miles over nine years—approximately 4,232 miles annually—indicates unusually light usage for a vehicle of this age. The gap between the 2022 test (20,327 miles) and the 2023 failure (32,691 miles) suggests a prolonged period of inactivity, as the mileage increase over 14 months (12,364 miles) is unusually rapid compared to the preceding years. This pattern could imply either infrequent driving or extended storage, both of which may accelerate degradation in fluids, tyres, and rubber components. The 2023 failure at 32,691 miles, despite passing the previous test just ten days earlier at 32,698 miles, is notable but lacks specific defect details—raising suspicion of a minor oversight rather than a systemic issue. Given the clean MOT history, a buyer should prioritise an inspection of suspension components, particularly the rear bushes and coil springs, which often degrade without visible external corrosion. The brakes, while not explicitly failed, warrant closer examination for uneven wear, binding calipers, or excessive dust accumulation, as these issues frequently develop gradually. Structural integrity should also be assessed for signs of corrosion in wheel arches, sills, or the subframe, especially if the vehicle has spent time in wet or salted environments. Fluid levels—brake, power steering, and engine oil—should be checked for degradation or contamination, as prolonged inactivity can lead to sludge formation. Finally, the tyres, despite passing MOTs, may require inspection for uneven wear patterns or low tread depth, as the 2023 failure suggests basic upkeep was occasionally skipped.
