2017 Mercedes-Benz CLA 2.0L Petrol · HJ66 ACK

The 2017 Mercedes-Benz CLA presents a notably clean roadworthiness record across four consecutive annual MOT tests, with the most recent pass on 2 June 2025 showing no recorded defects or advisories. This follows identically clean outcomes on 6 June 2024, 23 June 2023, and 5 July 2022. The absence of any advisories, corrosion notes, or component wear flagged over a four-year testing window suggests the vehicle has not exhibited the usual progressive deterioration that typically appears on a nine-year-old car, such as suspension bush play, brake disc lipping, or exhaust mounting degradation. While the lack of recorded advisories is a positive indicator under MOT criteria, it does not constitute proof of mechanical soundness, as the MOT test is a statutory roadworthiness check rather than a comprehensive mechanical inspection. The stable, defect-free trend across all recorded years indicates no pattern of recurring or worsening issues under test conditions. With a recorded mileage of 48,171 miles over approximately nine years, the annual accumulation rate sits at roughly 5,352 miles, which is notably low for the vehicle's age. The testing history shows annual tests from 2022 through 2025 with no multi-year gaps or extended off-road periods recorded in the DVSA data, indicating the vehicle has been in regular use throughout the testing period despite the modest mileage. Low annual mileage reduces wear rates on major drivetrain and suspension components relative to higher-mileage counterparts, but it can also introduce specific concerns. Perished rubber components such as suspension bushes, anti-roll bar links, engine and subframe mounts, and brake flex hoses can deteriorate with age independent of mileage. Brake discs and calipers are also susceptible to corrosion and binding after prolonged periods of light use, and brake fluid degradation occurs over time rather than purely through mileage accumulation. Given the absence of any flagged components in the MOT record, a prospective buyer cannot rely on the test history to identify specific wear items, making a hands-on inspection essential. On a test drive, listen carefully for any clonks or knocks from the front suspension when traversing speed humps or uneven surfaces, paying particular attention to the lower wishbones, anti-roll bar drop links, and top mounts, as Mercedes-Benz CLA models of this era are known to develop play in these components. Evaluate brake feel for any judder through the pedal or pulsation under heavy braking, which would indicate disc lipping or warping from corrosion rather than wear. Steering should remain precise and self-centring without any pulling to either flank under steady throttle or braking, and any vagueness on centre could point to worn tie rod ends or track rod bushes that an MOT would not necessarily flag. Additionally, a thorough physical inspection should include checking for oil leaks or dampness on the engine block, turbo, and from the oil filter housing, as Mercedes-Benz M270 and OM651 engines in this generation are known for sealing degradation. Inspect the underside for any surface corrosion on subframe and suspension arms, particularly given the low mileage which can paradoxically accelerate underbody corrosion if the vehicle has been used predominantly for short journeys in damp conditions. Verify that the dual-clutch automatic transmission changes smoothly without shudder on low-speed pull-away, and confirm full operation of all electrical systems including the infotainment screen, climate control, and central locking. Finally, given the low recorded mileage, confirm the timing chain or cambelt replacement interval status with supporting documentation, as age-based service schedules apply regardless of odometer reading.
