2015 Mercedes-Benz CLS 2.1L Diesel · SM65 AAX

The Mercedes-Benz CLS presents a clean MOT history, with both the August 2021 and August 2022 tests passing without any defects at 29,050 and 41,739 miles respectively. This indicates a stable maintenance trend, with no recurring issues or advisories to suggest neglect or progressive mechanical deterioration. The absence of even minor faults—such as tyre tread or wiper blade wear—implies either meticulous upkeep or, more likely, very light usage. For a vehicle of this age and mileage, such a pristine record is uncommon and raises the possibility of extended periods in storage or infrequent driving. The mileage accumulation is exceptionally low, averaging just 3,794 miles per year over its 11-year lifespan. Between the two recorded MOTs, the car covered 12,689 miles in 12 months, a rate that would be typical for a daily driver but is unusually high for this vehicle’s overall history. The gap between the 2021 and 2022 tests—just 12 months—suggests the owner has maintained regular testing, though the lack of earlier records leaves some uncertainty about its condition before 2021. Given the low annual mileage, wear on high-use components like brakes, suspension bushes, and clutch (if automatic) should theoretically be minimal, but this also means fluids may have degraded slowly over time. For a prospective buyer, the primary focus should be on components that degrade even with minimal use, such as brake fluid condition, suspension integrity (particularly coil springs and anti-roll bars), and signs of corrosion in hidden areas like wheel arches or underseal. The absence of MOT advisories does not guarantee these are flawless, so a pre-purchase inspection should include a thorough check of brake calipers for binding or fluid leaks, suspension bushes for hardening or splits, and tyre sidewalls for micro-cracking. Given the car’s age, the battery and electrical systems—often overlooked in low-mileage vehicles—should also be tested, as corrosion or sulphation can occur regardless of mileage. The clean MOT history is a strong indicator of careful ownership, but the lack of recent testing (nearly four years overdue as of July 2026) means some deferred maintenance could now be present.
