2018 Mercedes-Benz GLC 3.0L Diesel · B7 MBA

A consistent pattern of clean MOT results over the last three years follows a period of tyre-related failures and advisories between 2021 and 2023. While the vehicle failed in February 2021 due to a major defect regarding a cut in the offside rear tyre and received several advisories concerning front tyre tread wear and edge damage, the most recent test on 11 March 2026 shows no recorded defects. This indicates that the previous issues with tyre integrity and tread depth have been addressed, moving the vehicle into a period of recorded stability regarding its immediate roadworthiness. The recorded mileage of 62,721 miles against an eight-year age profile results in an average annual accumulation of approximately 7,840 miles. This usage level is consistent with typical UK driving patterns for a premium SUV of this age. Mechanically, this moderate mileage suggests that while consumables such as brake pads, discs, and suspension bushes will have undergone standard wear cycles, the vehicle has not been subjected to the high-frequency component fatigue associated with heavy long-distance motorway use or the potential stagnation issues seen in much lower-mileage examples. Prospective buyers should focus their physical inspection on the tyre condition and wheel alignment, given the history of cuts and uneven tread wear recorded in earlier tests. Although the 2026 MOT was clear, the previous advisories for tyres wearing on the edges or having cuts across the tread suggest that alignment or suspension geometry may have been an issue in the past. During a test drive, pay close attention to any steering pull to one side or vibrations through the steering wheel at varying speeds, which could indicate lingering alignment issues or uneven tyre wear. Additionally, because the 2021 and 2023 records specifically flagged tyre integrity and tread depth, it is prudent to inspect the current sidewalls and tread patterns of all four tyres for any signs of bulging, cracking, or unevenness. While no specific suspension components like wishbones or dampers were flagged for failure, the history of uneven tyre wear warrants a close look at the condition of the suspension bushes and steering linkages. Listen for any rhythmic knocking or clunking sounds when traversing uneven surfaces, which would indicate wear in the suspension assembly that could contribute to the tyre issues previously noted.
