2015 Mercedes-Benz C 2.1L Diesel · GC65 GEE

The vehicle’s most recent MOT test on 2026-03-12 confirms it remains roadworthy, though the single advisory—rear brake pads wearing thin at 1.1.13(a)(ii)—demonstrates a clear trend of progressive wear rather than acute failure. The absence of defects in the four preceding tests suggests no worsening structural or safety-critical issues, but the recurring brake advisory indicates routine attention is required. The 2026 test occurred just four months ago, which is within the standard MOT cycle, though the 11-month gap between tests (March 2025 to March 2026) is acceptable given the vehicle’s age. No major advisories or failures have escalated, but the thin rear pads—now at 98,878 miles—will need replacement soon to avoid binding calipers or uneven wear. The mileage progression of roughly 8,989 miles annually aligns with typical usage for a vehicle of this age, with no abrupt spikes or prolonged inactivity. The recorded mileage increments are consistent: 6,428 miles between 2022 and 2023, 8,601 between 2023 and 2024, and 7,314 between 2024 and 2025, before reaching 98,878 at the latest test. There is no evidence of excessive wear from high mileage or neglect from low usage, though the lack of service records beyond MOTs means internal maintenance (timing belts, fluid changes, suspension servicing) remains unverified. The 2022 test noted underbody floor covers, a minor but sensible modification to mitigate corrosion risk. A prospective buyer should prioritise an independent inspection of the rear brake system, particularly the pads and calipers, given the advisory from March 2026. The front brakes were not flagged in any test, but cross-checking for uneven wear or binding is advisable. At this mileage, the suspension bushes and coil springs should be examined for cracking or excessive play, while the exhaust system warrants scrutiny for leaks or corrosion, especially under the vehicle. Given the age and mileage, the engine bay should be inspected for fluid leaks, belt tension, and the integrity of hoses—particularly coolant and power steering lines. Rust penetration in wheel arches, sills, or the subframe is another critical area, as is the condition of the windscreen washer jets and wiper blades, which were not tested in any recent MOT.
