MERCEDES-BENZ S-Class2003 · 3.2L Diesel

The 2003 Mercedes-Benz S-Class presents a currently roadworthy status, having passed its most recent MOT on 21 July 2023 at 152,504 miles with no defects recorded. The maintenance trend across the available history is stable, showing no advisories or mechanical faults flagged by testers between 2020 and 2023. A minor anomaly appears in July 2023 when the car failed on 12 July at 152,504 miles yet passed nine days later at identical mileage with no defects listed, which suggests an administrative or documentation issue rather than a genuine mechanical defect. Annual mileage averages around 6,631 miles, typical for a 23-year-old vehicle. The records show steady accumulation: 106,988 miles in July 2020, 120,140 in July 2021, 139,854 in June 2022, and 152,504 by July 2023. The roughly 12,000 to 13,000 miles added each year indicates consistent but moderate use with no prolonged standing or sudden high-mileage spikes. The DVSA data is sparse on detail, listing no advisories across five tests, so the clean pass rate gives limited insight into component wear beneath the surface. A buyer should still commission an independent inspection of suspension bushes, coil springs, and brake discs given the vehicle's age and 152,504 miles of service. The S-Class air suspension is prone to ageing, and the MOT record's lack of advisories does not confirm these components remain within tolerance. Structural corrosion around subframes and sills should be physically checked despite no tester flags in the supplied history. The repeated clean tests imply previous owners kept basic statutory compliance but offer no evidence of proactive mechanical care beyond MOT minimums. Given the nine-day fail-pass in July 2023 at unchanged mileage, verify the V5C and DVSA gateway entry to confirm no suppressed defect. Pre-purchase checks on exhaust emissions and drivetrain condition remain advisable on a two-decade-old luxury saloon.
