2021 Mercedes-Benz E 300 AMG Line NGT ED Prem + A 2.0L Petrol · WG70 KUB

The 2021 MERCEDES-BENZ E 300 AMG LINE NGT ED PREM has presented a motoring history characterised by intermittent mechanical challenges rather than consistent reliability. The most recent MOT examination conducted on 2026-02-16 returned a passing result with no defects recorded, indicating the vehicle has remained operationally functional in its latest review. However, this positive outcome follows two distinct problem episodes: a failed MOT on 2025-01-22 that cited major deficiencies with both front and rear registration plates not meeting specification requirements, and a 2024-01-22 test that issued multiple advisory warnings regarding tyre wear across all four positions. The pattern suggests the car has not been continuously reliable but appears to have stabilised after the earlier failures, although the resolution of the registration plate issues remains unconfirmed in the latest test. With 38,392 miles recorded on a model approximately five years old, the vehicle accumulates roughly 7,678 miles annually, which aligns with typical consumption for its age group. The interval between the 2025-01-22 failure and the 2026-02-16 pass represents nearly eight months without a MOT, followed by a single-week gap before the most recent test, indicating the car has not required frequent servicing since January 2025. While this pace of mileage is within expected parameters for a seven-plus-year-old vehicle, the persistence of tyre advisories from early 2024 suggests that certain components may still be experiencing accelerated wear or underlying issues that will manifest over subsequent kilometres. The absence of additional major defects in the 2026-02-16 examination implies that the vehicle has largely held together mechanically since resolving the earlier registration plate and tyre concerns. The front tyres on all four wheels are currently flagged as worn close to the legal limit according to the 2024-01-22 advisory, which carries the indicator 5.2.3(e). During a test drive, the buyer should pay particular attention to any abnormal vibrations when travelling over rough pavement, as worn tyres often transmit road imperfections through the suspension and can cause uneven braking force distribution. Additionally, the worn edges may affect cornering stability and increase the likelihood of premature brake pad wear, so checking for excessive squeal or pulsations in the brake pedal while decelerating would be prudent. Regarding the registration plate failures recorded in January 2025, these are regulatory compliance issues that require immediate correction before the vehicle can be fully cleared for road use. The buyer should confirm that both front and rear registration plates meet the current DVSA specifications at the point of purchase. For the tyre situation, visual inspection of the tread depth combined with a road test should reveal whether the wear is uniform or concentrated, which would help determine if alignment adjustments or tyre replacement are needed. Given the high annual mileage, it is also advisable to inspect the brake discs and caliper mounting surfaces for any signs of heat soak or leakage, particularly around the rear axle where increased stopping demands may accelerate wear.
