2020 Mercedes-Benz GLC 300 AMG Line Prem D 4M A 1.9L Diesel · SH66 ABZ

The vehicle’s most recent MOT test on 30 May 2025—just 12 months prior to today—confirmed full compliance with all roadworthiness criteria at 62,622 miles, with no defects or advisories recorded. This clean history over three consecutive tests (2023, 2024, and 2025) suggests the vehicle has undergone consistent MOT-level maintenance, though it does not preclude undocumented wear or deferred repairs beyond the tester’s scope. The absence of recurring advisories or failings on suspension bushes, coil springs, binding calipers, or structural corrosion implies no obvious pattern of neglect. However, the lack of advisory notes also means critical components like turbocharger seals, differential fluid, or power steering hoses were not specifically inspected, leaving those areas as potential blind spots. The recorded mileage progression—10,437 miles annually—falls within the expected range for a vehicle of this age, with no abrupt spikes or prolonged stagnation. The intervals between tests (around 9,300 miles) align closely with the 12-month MOT cycle, indicating regular use without extended periods of disuse that could accelerate corrosion or component degradation. There is no evidence of mileage tampering or inconsistent odometer readings, though the buyer should verify the accuracy of this figure against service records if available. Given the clean MOT history, the primary focus for an in-person inspection should centre on high-wear items not routinely tested. The suspension—particularly the rear coil springs and bushes—should be examined for uneven sagging or excessive play, as these are common points of failure in AMG-line vehicles. Brake discs and pads, while not failed in MOTs, may show uneven wear patterns, and the tester’s failure to note binding calipers in prior tests warrants a check for seized rear wheel bearings or warped rotors. The underbody should be scrutinised for signs of corrosion around the sills, subframe, and exhaust mounts, as these areas are prone to hidden deterioration even when the vehicle passes MOT standards. The engine bay requires attention to fluid levels and condition, particularly the turbocharger oil seals, which are often overlooked until leaks develop. The differential and transfer case fluids should be inspected for discolouration or contamination, as these are less frequently checked than engine oil. Finally, the electrical system—including battery health, wiring harness integrity, and sensor functionality—should be tested, as MOT tests do not comprehensively evaluate these components. A pre-purchase diagnostic scan can reveal any stored fault codes that might indicate underlying issues.
