2017 Mercedes-Benz S-Class 2.9L Diesel · GSZ 3025

The 2017 Mercedes-Benz S-Class presents a clean roadworthiness status with a stable maintenance trend, confirmed by the most recent test on 12 December 2025 at 95,374 miles where the tester recorded no defects. Every annual examination from 2022 through 2025 returned a pass with no advisories, indicating the vehicle has not entered a pattern of recurring faults or escalating wear. Annual mileage sits at roughly 10,600 miles, typical for a nine-year-old executive saloon. The records show steady accumulation: 57,092 miles in June 2022, 61,175 by December 2022, then 75,081 in December 2023, 81,757 in November 2024, and 95,374 in December 2025. No abrupt jumps or standing gaps appear. The DVSA data is sparse in detail yet consistently clean, which suggests the previous keeper maintained the car to a standard that avoided even minor consumable flags such as tyre tread or wiper wear. A buyer should still commission an independent inspection of suspension bushes, coil springs, and brake discs given the age and near-100,000-mile count, as these components accumulate fatigue absent from a fault-free MOT sheet. The S-Class air suspension in particular warrants a live check for compressor health and strut leaks, neither of which a visual MOT routinely stresses under load. Structural integrity and underbody corrosion require a ramp assessment despite the absence of advisories across five tests. The clean record implies disciplined upkeep, but nine years of road salt exposure can hide early subframe scaling. Verify service history aligns with the recorded mileages before purchase.
