2017 Mercedes-Benz S-Class 4.7L Petrol · 4 SHS

The 2017 Mercedes-Benz S-Class presents a stable and exemplary maintenance trend, culminating in a completely clean pass at its most recent MOT on 3 June 2025 at 22,609 miles. The tester recorded zero defects, advisories, or failures across the entire five-year history. This unblemished record indicates a vehicle that has suffered no mechanical deterioration or structural corrosion, reflecting a fastidious approach to preventative maintenance by the previous keeper. The absence of recurring faults demonstrates a resolving trend, where the car has remained in optimal operating condition year after year. The mileage accumulation is remarkably low and highly consistent for a vehicle of this age. Between the 2021 test at 14,038 miles and the 2025 test at 22,609 miles, the odometer advanced by just 8,571 miles over four years, averaging roughly 2,142 miles annually. This pattern points to very light, localized usage rather than long-distance touring. Such low annual mileage typically minimizes wear on consumables like brake discs, suspension bushes, and drivetrain components, though it raises the question of prolonged stationary periods that can cause perishable rubber components to dry out or brake calipers to bind. Despite the flawless MOT record, a prospective buyer must inspect the vehicle for issues that MOTs do not always capture, particularly those stemming from low-mileage usage. Check the tyre sidewall dates for age-related cracking, as rubber degrades over time regardless of tread depth. Examine the brake discs for surface corrosion and listen for binding calipers, which can seize when a car sits idle for extended periods. Inspect the suspension bushes and air springs for perishing or cracking. Finally, verify the condition of the exhaust system and underbody for any early signs of corrosion, ensuring the structural integrity remains intact despite the minimal mileage.
