2009 Mercedes-Benz CLK 1.8L Petrol · SP09 YWV

The 2009 Mercedes-Benz CLK presents a mixed roadworthiness picture defined primarily by a pattern of recurring tyre and braking system advisories that span nearly two decades of ownership. The most recent MOT conducted on 2026-06-01 returned a clean result with no defects, yet this passing result sits atop a consistent trail of warnings beginning in 2018 and continuing through 2020, including multiple instances of tyres worn close to the legal limit on various axle positions and repeated corrosion alerts on rear brake pipes. These advisories—particularly the persistent nearside front and rear tyres showing edge wear and the recurrent brake pipe corrosion—create a mechanical narrative of gradual degradation rather than sudden failure, with the car having accumulated approximately 78,681 miles over its 17-year life at an average rate of just under 4,600 miles per year, which is notably lower than typical consumption for a vehicle of this age. The mileage figure raises important questions about the vehicle's actual usage profile compared to its stated age. A 17-year-old car typically accumulates closer to 100,000–120,000 miles when driven regularly, so the current reading suggests either very limited annual mileage or extended periods of storage interspersed with short bursts of driving. The absence of a prolonged gap between the 2020 and 2021 MOTs indicates continuous registration activity, while the steady progression of tyre wear across different positions implies that the wheels have been subjected to uneven loading or possibly misalignment over the years. When combined with the repeated brake pipe corrosion findings, the usage pattern hints at a vehicle that may have spent significant time parked or in mild operation cycles, allowing small-scale deterioration to accumulate before becoming apparent in the MOT records. Focus on the documented advisories reveals two primary areas requiring close attention during a test drive. The tyre wear flags—nearside front, nearside rear, and offside rear—should be inspected for signs of uneven wear patterns that could indicate alignment issues, camber problems, or differential wear inconsistent with normal driving conditions; listening for knocking over potholes or feeling for vibration through the chassis will help determine whether the suspension bushings, control arm bushings, or wheel bearings have developed excessive play or looseness. The brake pipe corrosion alerts demand particular scrutiny: check for visible rust buildup inside the pipe fittings, any dripping or leaking brake fluid, and ensure the parking brake engages firmly with no spongy pedal response. Given the recurrence of this specific defect since late 2020, the brake system may have suffered cumulative damage from oxidation or physical impact, and a professional inspection of the brake line routing and fluid condition would be prudent before committing to purchase.
