2018 Mercedes-Benz S-Class 4.0L Petrol · LF18 WFX

The vehicle presents a high standard of roadworthiness, evidenced by a consistent history of clean MOT passes. The most recent test conducted in November 2025 at 42,058 miles returned no defects or advisories, indicating a stable maintenance trend. This streak of clean results suggests the vehicle has been maintained to a high standard without the recurring mechanical failures or structural degradation typically seen in luxury vehicles of this age. The mileage profile is notably low for an eight-year-old vehicle, averaging approximately 5,257 miles per year. Between the March 2022 test at 15,503 miles and the November 2024 test at 39,808 miles, the car covered over 24,000 miles, representing a significant spike in usage compared to previous years. However, the overall mileage remains well below the national average for an S-Class. This low usage generally reduces wear on drivetrain components and suspension, though it increases the risk of age-related perish in rubber seals and fluid-related issues due to periods of inactivity. While the MOT record shows no flagged faults, a physical inspection should focus on specific areas common to low-mileage S-Class models. The buyer should verify the condition of the air suspension system for leaks or sagging, as rubber components can perish over time regardless of mileage. The brake discs should be checked for corrosion or pitting, as infrequent use often leads to surface rust that causes uneven wear. Checking the undercarriage for any structural corrosion will also ensure the integrity remains intact as reflected in the clean test history.
