2009 Mercedes-Benz S-Class 5.5L Petrol · SF09 UCT

The 2009 Mercedes-Benz S-Class presents a stable and clean roadworthiness profile. The most recent test on 30 September 2025 at 95,441 miles returned a pass with no defects recorded, and this follows four consecutive annual passes with zero advisories. The maintenance trend is steady with no worsening or recurring mechanical faults across the five-year DVSA record. The odometer shows low use for a seventeen-year-old vehicle. Mileage rose from 85,551 on 27 September 2021 to 95,441 by 30 September 2025, an average of roughly 2,472 miles per year against a lifetime mean near 5,614. The clean record shows no gaps in testing and no rapid accumulation; each September test captured modest annual increments of 2,000 to 2,900 miles, implying light, consistent running rather than neglect or heavy touring. A buyer should still commission an independent inspection despite the unblemished MOT trail. Low annual mileage combined with age raises the risk of perished suspension bushes, degraded rubber components, and standing-vehicle corrosion on structural subframes that a visual test may not flag without strip-down. Brake discs and calipers may show superficial rust from disuse even where the tester recorded no binding or efficiency loss. The S-Class air suspension and exhaust emissions systems warrant particular attention given the model's complexity and the car's long idle periods between tests. Verify the compressor operation and strut condition in person. The absence of advisories suggests prior owners kept basic upkeep current, but the record alone cannot confirm hidden wear on consumables or intermittent faults absent on test day.
