2021 Mercedes-Benz C 220 AMG Line NGT ED Prem D A 1.9L Diesel · SP11 LZP

The recorded MOT history for this 2021 C 220 AMG Line presents a notably clean roadworthiness profile, though it is anchored by a specific pattern of tyre wear that warrants direct attention. Across three documented tests spanning from May 2024 through March 2026, the vehicle has passed each inspection without recorded failures or advisories other than tyre condition. The March 2026 test, the most recent, was completed with no defects recorded at all, which aligns with a stable and untroubled structural and emissions picture. However, the March 2025 test flagged both rear tyres as worn close to the legal limit and worn on the edge, a defect that tends to indicate either an alignment irregularity at the rear axle or a toe setting that is outside specification. Because this advisory appeared only on the rear axle and on both sides simultaneously, it is mechanically suggestive rather than a simple consumable issue and is worth verifying during a physical inspection. With approximately 25,646 miles recorded over five years, the vehicle has accumulated an average of roughly 5,129 miles annually, which is low for a car of this age and segment. This mileage profile implies light to moderate use, which generally means lower cumulative wear on friction components such as brake discs, pads, and clutch material, and reduced stress on internal drivetrain parts. Conversely, low annual mileage can be associated with extended periods of standing, which can produce dry corrosion on brake discs, flat spots on tyres that have remained stationary under load, and degraded rubber components throughout the suspension and drivetrain seals. The fact that the rear tyres were already worn to near-legal limits by March 2025, when the vehicle would have been roughly four years old, does raise a question about whether the wear is genuinely mileage-driven or the result of a geometric issue at the rear axle, as the mileage itself is not high enough to naturally consume two rear tyres within that interval. Given the specific advisory on both rear tyres showing edge wear, a prospective buyer should prioritise a thorough physical check of the rear suspension geometry. On a test drive, listen for any knocking or clonking from the rear axle over uneven surfaces, particularly speed humps and expansion joints, as this would suggest worn rear suspension bushes, top mounts, or spring seats. Steering should be checked for any pulling or drifting, especially under braking, which can reveal a sticking or binding rear caliper. Visually, the rear tyres should be inspected for feathering or one-sided wear patterns across the tread blocks, and the tracking should be confirmed with a four-wheel alignment check rather than relying on a front-only setting. Additionally, the buyer should examine the inner and outer edges of all four current tyres for uneven wear, as a recurrence of the pattern recorded in the MOT history would confirm an unresolved alignment or suspension concern rather than a one-off tyre issue. Beyond the tyre history, the absence of any recorded advisories relating to brake pipes, underbody corrosion, fluid leaks, or suspension components across the three tests suggests the chassis and mechanical underpinnings have not yet raised MOT-level concerns. That said, given the relatively low annual mileage, the buyer should still perform a careful inspection of the brake discs for surface rust and lipping, particularly on the rear axle, as prolonged standing followed by light braking can produce uneven disc wear. The exhaust system, particularly on an estate variant such as this with NGT factory-fitted components, should be checked for blueing at joints, corrosion around mounting rubbers, and any signs of condensate leakage at the rear silencer. Finally, given that the vehicle is an automatic diesel with factory NGT natural gas preparation, an extended diagnostic scan covering injector balance, DPF regeneration history, and any stored NGT system codes would be prudent, as MOT testing does not interrogate these powertrain management systems and the clean MOT record cannot confirm their internal health.
