2020 Mercedes-Benz GLC 1.9L Diesel · 80 NS

A consistently clean MOT record defines this 2020 Mercedes-Benz GLC, with three consecutive passes on file and only a single advisory raised across all tests. The most recent examination on 19 June 2026 returned a pass with no defects recorded, continuing a stable pattern stretching back to June 2023. That earlier test noted a nearside rear tyre worn close to the legal limit on its edge, but no further tyre-related advisories have appeared since, suggesting the issue was addressed at the time and has not recurred. There are no recorded advisories concerning suspension components, brake condition, corrosion, structural integrity, exhaust emissions, or fluid leaks anywhere in the history, which collectively points to a vehicle that has maintained its roadworthiness presentation throughout its testing life. At 91,326 miles over roughly six years, this GLC has accumulated approximately 15,200 miles annually, a notably high figure for a premium SUV of this vintage. This places it firmly above average mileage and means wear-related deterioration of consumables and mechanical components should be expected to be further advanced than on a lower-mileage equivalent. The annual MOT cadence is consistent, with tests completed each June over 2023, 2024, 2025 and 2026, indicating the vehicle has been in regular use rather than left standing for extended periods. The absence of advisories despite this higher-than-average usage is a positive signal, but it does not offset the reality that high-mileage GLCs typically show more pronounced component wear as they progress beyond the 90,000 mile threshold. From a buyer inspection standpoint, the clean MOT history permits a focused rather than reactive appraisal. Given the previous advisory on the nearside rear tyre wearing on its edge, inspect all four tyres for uneven shoulder wear, which on a GLC can hint at rear suspension geometry issues, worn trailing arms, or alignment drift particularly under heavy load. On a test drive, listen for clonking or knocking noises from the rear suspension over uneven surfaces, as the multi-link rear arrangement fitted to this model is known to wear its bushes and control arm joints earlier under high mileage. Pay particular attention to any vagueness in the front end or uneven tyre wear across the front axle, which would suggest the front lower wishbones or steering tie rods may now be approaching replacement intervals despite not yet being flagged at test. Brake-related checks should also take priority given the mileage profile. Although no brake defects have been recorded, discs and pads on a high-mileage GLC will typically have been replaced at least once. On the test drive, feel for any vibration or judder through the steering wheel or a pulsating brake pedal under firm application, as this suggests warped front discs. Listen for any scraping or grinding noises that would indicate pads worn close to backing plate, and check for pulling to one side under braking which could point to a binding caliper. Finally, with the odometer now well into six-figure territory, inspect for any signs of oil seepage from the engine and transmission areas, as well as the condition of the underbody protection panels, both of which become increasingly relevant as mileage accumulates but would not necessarily have been captured as advisories unless visible at MOT level.
