2020 Mercedes-Benz E 400 AMG LN NGT ED Prm+d 4M A 2.9L Diesel · KP20 UFD

The Mercedes-Benz E 400 AMG LN NGT has demonstrated a stable roadworthiness record over its most recent MOT cycles, with the February 2026 test at 38,793 miles showing no defects—a clear improvement from the February 2025 entry. At that earlier test, the tester noted only minor cosmetic issues: a slightly damaged offside rear tyre and a front windscreen scratch that did not impair visibility. These were not mechanical failures but rather indications of superficial neglect, likely addressed promptly given their absence in subsequent tests. The lack of recurring advisories or failures in structural, braking, or suspension components suggests the vehicle has been maintained conscientiously in critical areas, though the short interval between tests (just over a year) means wear on high-mileage items like tyres, brakes, and suspension bushes should still be verified before purchase. The mileage accumulation of 6,466 miles per year aligns closely with the average for a vehicle of this age, reflecting either light but consistent use or periods of inactivity. The recorded mileages—19,118 in March 2023, 25,981 in March 2024, 32,903 in February 2025, and 38,793 in February 2026—show steady but not aggressive driving, which typically reduces stress on drivetrain and suspension systems. The absence of rapid mileage spikes or prolonged gaps (beyond the standard annual testing cycle) implies no extreme usage patterns, though the low annual mileage could mask deferred maintenance on less critical components. The most recent MOT’s clean pass at near-40,000 miles further supports that the vehicle has not been pushed beyond its expected service intervals. For a prospective buyer, the primary focus should be on verifying the condition of consumables and wear-prone parts not covered by the MOT. While tyres were flagged once for superficial damage, a closer inspection of tread depth, sidewall integrity, and rotation history is advisable—especially given the AMG’s performance-oriented handling. Braking components, including pad thickness, disc condition, and caliper operation, should be checked for uneven wear or corrosion, as the MOT does not require disassembly. Suspension components—such as coil springs, dampers, and bushings—should be assessed for leaks, excessive movement, or signs of binding, particularly on the rear axle where the 2025 tyre advisory might hint at alignment or load-bearing issues. Structural integrity, including sills, wheel arches, and underbody corrosion, should also be scrutinised, as the MOT does not inspect hidden areas beyond visible rust penetration. The clean test history is encouraging, but a pre-purchase inspection by a Mercedes-specialist mechanic would be prudent to confirm no deferred maintenance exists beyond what the MOT captures.
