2017 Mercedes-Benz C 220 AMG Line Premium D Auto 2.1L Diesel · M23 BBB

This Mercedes-Benz C 220 AMG Line Premium demonstrates a consistently stable roadworthiness record, with every MOT test since 2021 passing without defects or advisories. The most recent inspection on 30 September 2025—just under ten months ago—confirmed no issues, placing the vehicle well within the DVSA’s recommended 12-month retest window. The absence of recurring advisories or failings suggests the car has been maintained at a baseline level, though this does not preclude hidden wear in high-stress components like the turbocharged engine or drivetrain. The mileage progression of approximately 10,500 miles annually aligns with typical usage for a vehicle of this age, without abrupt spikes or prolonged stagnation. The recorded mileage jumps from 40,803 miles in August 2021 to 54,559 by September 2022—a 13,756-mile increase—indicating steady, regular use rather than neglect. There are no extended gaps where the vehicle might have remained stationary, which could have accelerated corrosion or suspension degradation. However, the lack of service history beyond MOTs means critical intervals for fluid changes, timing belt checks, or AMG-specific maintenance may have been overlooked. Given the clean MOT record, a buyer should prioritise an independent inspection of the turbocharged engine’s oil condition and carbon buildup, particularly given the AMG Line’s performance tuning. The suspension—including coil springs, bushes, and dampers—should be scrutinised for uneven wear or binding, as these components often fail silently after prolonged use. Brake calipers and discs, especially on the rear where binding was not recorded but could develop over time, warrant close examination. Finally, the underbody and wheel arches should be inspected for corrosion, as the C-Class is prone to rust progression in critical areas like the subframe or control arms, even when MOTs pass without mention.
