2018 Mercedes-Benz GLC 4.0L Petrol · AS63 SDS

The most recent MOT test passed in December 2025, but the results indicate a transition from a clean maintenance history to one involving mechanical wear. While the vehicle has successfully passed its inspections, the presence of braking advisories suggests a downward trend in the condition of consumables compared to the defect-free record seen in 2022. The significant failure in late 2024 due to dangerous tyre wear also points to a period where routine maintenance checks may have been overlooked, meaning a thorough inspection of all recent replacement parts is necessary to ensure the vehicle is currently being maintained to a high standard. With 84,528 miles recorded over approximately eight years, the vehicle has averaged roughly 10,566 miles per year. This level of usage is consistent with typical UK driving patterns for a premium SUV and suggests the vehicle has not been subject to excessive motorway mileage nor long periods of stationary neglect. This consistent usage profile is generally beneficial for preventing component seizure and fluid degradation, but at this mileage, the vehicle is entering a phase where more intensive maintenance on suspension, drivetrain, and cooling systems is expected. A primary concern for a prospective buyer is the braking system, specifically the advisories regarding pitted rear discs and a binding nearside front caliper. On a test drive, you should pay close attention to any rhythmic grinding or squealing noises during deceleration, and feel for any shuddering or vibration through the brake pedal, which would indicate uneven disc surfaces. A binding caliper can lead to overheating and premature wear of the brake pads and even the wheel bearings; check for excessive heat or a distinct burning smell coming from the nearside front wheel after a short period of driving. Additionally, given the previous dangerous failure involving exposed tyre cords, you must carefully inspect the current tyres for sufficient tread depth and any signs of uneven wear that could signal alignment or suspension issues. You should also listen for any clunks or knocks from the suspension when driving over uneven surfaces, as the bushes and coil springs may be nearing the end of their service life. Finally, ensure that the service history is documented and that fluid changes, such as brake fluid and engine oil, have been performed according to the manufacturer's intervals rather than solely based on mileage.
