2018 Mercedes-Benz S-Class 3.0L Petrol · AC66 FUN

The 2018 Mercedes-Benz S-Class presents a clean roadworthiness status. The most recent test on 19 March 2026 at 72,881 miles passed with no defects recorded, and the maintenance trend across the full history is stable, with every annual examination returning a pass and no advisories logged at any stage. Mileage accumulation shows an irregular pattern against the vehicle's eight-year age. The March 2023 test recorded just 25,898 miles, yet by October 2023 the car had reached 50,402 miles, a surge of over 24,000 miles in under seven months. A further 4,266 miles appeared by March 2024 at 54,668 miles, then a striking drop to 41,041 miles at the March 2025 test suggests a possible odometer correction, private plate transfer, or data entry anomaly, before climbing again to 72,881 by March 2026. Average use sits near 9,110 miles per year, but the record is sparse and inconsistent rather than a smooth curve. No tester flagged suspension bushes, coil springs, brake discs, binding calipers, corrosion, or exhaust emissions faults across the five examinations. The absence of advisories implies previous owners addressed wear before each test or the car saw gentle use in patches. A buyer should still commission an independent inspection of structural integrity and drivetrain mounts given the mileage spike in late 2023, and verify the 2025 mileage discrepancy with V5C and service records before purchase. Given the clean MOT trail, focus the viewing on tyre sidewall condition, underbody rust proofing, and electronic air suspension operation typical of the S-Class. The records show no recurring mechanical trend, so physical verification of the stated mileages remains the priority rather than rectifying past failures.
