2018 Mercedes-Benz S-Class 4.0L Petrol · GU68 WLG

The vehicle presents a stable and unblemished maintenance trend, evidenced by a flawless pass rate across all recorded MOT tests. The most recent examination on 1 September 2025 at 38,148 miles recorded zero defects, confirming the S-Class currently meets all UK roadworthiness standards without advisories, though this certificate approaches its expiry in September 2026. This consistent pass record indicates the mechanical and structural integrity remains sound. The mileage accumulation is notably low for an eight-year-old vehicle, averaging roughly 4,768 miles annually. Between the 2021 test at 31,976 miles and the 2022 test at 36,092 miles, the car covered 4,116 miles in just under twelve months. Usage dropped significantly thereafter, with only 1,554 miles added between October 2022 and October 2023, and a mere 502 miles recorded between October 2023 and September 2025. A notable gap exists between the 2023 and 2025 tests, spanning nearly two years instead of the standard annual interval, suggesting prolonged periods of standing rather than active driving. Despite the absence of mechanical or structural advisories in the official record, the extended periods of inactivity typical of this mileage profile warrant a focused physical inspection. Buyers should scrutinise the condition of the tyres for flat-spotting and sidewall perishing, as low-mileage vehicles often suffer from ageing rubber rather than tread wear. The braking system requires close examination for corrosion on discs and binding calipers caused by lack of use. Suspension bushes and air suspension components should be checked for deterioration from standing still. A thorough assessment of the exhaust system and fluid condition will confirm whether the infrequent use has caused moisture accumulation or degradation.
