2018 Mercedes-Benz S-Class 4.0L Petrol · AE07 CHR

The 2018 Mercedes-Benz S-Class presents a stable and exemplary maintenance trend, culminating in a completely clean pass at its most recent MOT on 23 February 2026 at 22,229 miles. The tester recorded zero defects or advisories, indicating the vehicle currently meets all required safety and emissions standards without compromise. This unblemished record across multiple tests suggests a fastidious ownership history where mechanical and structural integrity has been consistently maintained. The mileage accumulation aligns precisely with the vehicle's age, reflecting exceptionally light usage of roughly 2,779 miles annually. Between the August 2022 test at 8,427 miles and the July 2023 test at 11,506 miles, the car covered 3,079 miles over an eleven-month period. Subsequent annual intervals show a steady increase in usage, climbing from 12,868 miles in February 2024 to 16,220 miles in February 2025, and finally reaching 22,229 miles in February 2026. This accelerating mileage pattern indicates the vehicle has transitioned from prolonged periods of standing to more regular, recent use. Despite the flawless MOT record, a physical inspection remains essential due to the specific risks associated with low-mileage, long-term standing. Buyers should closely examine the condition of the tyres for flat-spotting and sidewall perishing, as infrequent use degrades rubber compounds unevenly. The braking system requires scrutiny for surface corrosion on discs and binding calipers, common issues when high-performance vehicles sit idle. Inspect the suspension bushes and air suspension components for deterioration, and check the underbody and structural mounting points for any corrosion that might not have triggered an MOT failure but could compromise long-term structural integrity.
