2009 Mercedes-Benz CLS 3.5L Petrol · RO51 SHE

The 2009 Mercedes-Benz CLS presents a stable roadworthiness trend with a clean pass at the most recent test on 2025-09-22 at 45,907 miles, where the tester logged no defects. Prior examinations show the same pattern of clean results, with passes recorded on 2024-09-13 at 37,918 miles, 2023-10-05 at 31,559 miles, and 2022-09-28 at 27,626 miles. The only anomaly appears on 2024-09-13, when the vehicle failed with no defects recorded before passing the same day, a likely administrative or documentation error rather than a mechanical fault. No advisories or recurring defects appear across the five-year span. At roughly 17 years old the car shows 45,907 recorded miles, an average of about 2,700 miles per year. The odometer advanced from 27,626 in September 2022 to 31,559 by October 2023, then to 37,918 by September 2024, and 45,907 by September 2025. That equates to annual use of 3,900, 6,359, and 7,989 miles in the last three periods, a gradual rise from very low early mileage but still below typical class averages. The sparse, defect-free record gives little evidence of neglected consumables, though long stationary periods implied by the low lifetime total raise the risk of perished rubber components and seized mechanisms. A buyer should still commission a physical inspection of suspension bushes, coil springs, and brake calipers for binding or corrosion, as low-use vehicles often hide such degradation until stressed. Examine brake discs for surface pitting from disuse and check exhaust emissions under load. Structural integrity around sills and subframes warrants a ramp check for hidden rust despite the clean MOT history. Given the absent advisories, previous keepers appear to have stored and maintained the car lightly rather than deferred work. Verify service records match the mileage jumps and confirm the 2024 same-day fail-pass was clerical, not a concealed repair.
