2019 Mercedes-Benz GLC 300 AMG Line Prem D 4M A 1.9L Diesel · FS55 HRS

A clean and uninterrupted record of roadworthiness defines this Mercedes-Benz GLC 300, with four consecutive passes at annual intervals from 2022 through 2025 and a single unrecorded fail on 22 October 2022 followed by a pass just two days later. The most recent assessment on 12 December 2025 returned a pass with no defects or advisories recorded, which is the strongest possible outcome under the DVSA testing regime and indicates that none of the inspected components—brakes, tyres, suspension, emissions, lights, or structure—were flagged for attention. The absence of advisories across every test entry is particularly noteworthy, as even well-maintained premium vehicles typically accumulate minor wear-related notes such as tyre tread depth approaching the legal limit, corrosion on underbody components, or slight brake component wear. The lack of any such entries points to a consistent mechanical condition rather than a vehicle that has been progressively deteriorating between tests. Against an expected annual mileage of roughly 6,602 miles per year given its seven-year age, the recorded 46,216 miles sits squarely within typical parameters, suggesting neither excessive motorway use nor extended periods of standing that might accelerate specific failure modes such as brake disc corrosion or dry-belt deterioration. The roughly even spacing between test dates—2022, 2023, 2024, and 2025—indicates the vehicle has been in continuous, regular use rather than laid up for multi-year stretches, which is favourable for drivetrain and component longevity. The only minor anomaly is the two-day gap between the 22 October 2022 failure and the subsequent pass on 24 October 2022, an interval short enough to suggest a straightforward retest after minor rectification rather than any extended off-road period. Although the DVSA record itself carries no advisories to act as a roadmap for inspection priorities, the prospective buyer should focus attention on the components most commonly associated with wear on a GLC of this vintage and mileage. The multi-link front suspension fitted to this model is known for premature wear of the lower control arm bushes and thrust arms, so on a test drive listen for clonking or knocking noises from the front end over speed humps and uneven road surfaces, and feel for vagueness or shudders through the steering wheel that could indicate worn drop links or track rod ends. The diesel variant should be checked for signs of oil leakage from the OM654 engine, particularly around the front crankcase sealing area, and any blue smoke on overrun or under hard acceleration would warrant investigation of the turbocharger and EGR system, neither of which would necessarily be flagged at MOT but are relevant to a 46,000-mile diesel. Brake system inspection should centre on the discs and pads, as even a clean MOT pass does not guarantee significant remaining friction material given that the test does not flag components until they are at or near the legal minimum. On the road, the buyer should test for any pulling to one side under braking, which would suggest a binding caliper, and listen for grinding or squealing that could indicate worn pads or scored discs. The 4MATIC all-wheel-drive system should be exercised gently on a loose surface if possible to confirm there is no binding or driveline shunt that might indicate propshaft or transfer case wear. Finally, a thorough underbody examination with the vehicle on a ramp is strongly advised to identify any corrosion on the subframe, brake pipe unions, or exhaust mounting points, even though none of these have been recorded by the DVSA, as a clean paper record on a seven-year-old vehicle is a positive indicator but not a substitute for direct physical inspection.
