2014 Mercedes-Benz S-Class 2.1L Electric diesel · 71 R

The most recent MOT, conducted on 7 April 2026 at 46,095 miles, resulted in a clean pass with no defects recorded. This continues an unbroken run of five consecutive passes stretching back to February 2022, none of which carried a single advisory. That record indicates a mechanically stable vehicle that has not suffered from recurring wear items, corrosion, or suspension deterioration over the past four years. The maintenance trend is firmly stable rather than merely improving, and the absence of any flagged issues at the last inspection is a strong indicator of sound current roadworthiness. The mileage profile shows steady, low-intensity use. The car covered 2,199 miles between the March 2025 test and the April 2026 test, having covered 2,713 miles in the previous year and 2,281 miles the year before that. Annual mileage has hovered consistently around the 2,200 to 3,500-mile mark, which aligns with the overall average of roughly 3,841 miles per year across its 12-year life. There are no suspicious gaps in the testing history and no sudden or prolonged periods of standing evident from the odometer readings. This pattern suggests a car that has been used regularly for short-to-moderate journeys rather than left idle for long stretches. Because the MOT history is completely clean, a buyer must look beyond the test certificates to uncover latent issues that routine inspections can miss. The MOT does not assess oil condition, brake fluid age, coolant state, or the health of the auxiliary drivebelt, and a 12-year-old S-Class will inevitably have aged rubber and fluid systems even at this low mileage. Pay particular attention to the air suspension, which is not always fully tested for slow leaks; listen for the compressor running excessively and check whether the car sits level after being parked overnight. Check the brake discs for lip corrosion from light use, inspect the underside for surface rust on subframes and suspension arms, and verify that the battery holds a full charge, as low annual mileage can strain the charging system. Finally, confirm that the service book shows regular oil changes at least every 12 months, irrespective of the low mileage, because a clean MOT history cannot guarantee that routine servicing has been kept up to date.
