2007 Mercedes CLK 3.5L Petrol · BM02 AAM

The vehicle most recently passed its MOT on 16 February 2026, but the overall maintenance trend is concerning and suggests a reactive rather than proactive approach to upkeep. There are several recurring advisories that have persisted over multiple years, specifically regarding the rear sub-frame corrosion and play in the nearside front steering rack inner joint. The recent failure in early 2026 due to parking brake efficiency and a deteriorated anti-roll bar linkage dust cover indicates that wear and tear items are reaching a critical point without being addressed preemptively. With a recorded mileage of 82,675 miles over nineteen years, the vehicle has averaged approximately 4,351 miles per year. This is significantly lower than the UK average, which often implies the car has spent extended periods stationary. While low mileage reduces general drivetrain wear, it frequently exacerbates issues related to corrosion and the perishing of rubber components. In this instance, the low usage likely contributes to the observed brake disc pitting and the onset of structural corrosion on the sub-frame and suspension mountings, as moisture and salt can settle on stationary components. A prospective buyer must pay close attention to the steering and braking systems during a physical inspection and test drive. The persistent advisory for play in the steering rack inner joint should manifest as a slight vagueness in steering precision or a clicking sound when turning the wheel at low speeds. Given the history of parking brake failure and previously corroded brake pipes, the buyer should check for binding calipers or a spongy pedal feel. The recurring mention of pitted brake discs suggests that the braking system may suffer from surface oxidation due to inactivity, which can lead to shuddering under heavy braking. The most critical area for inspection is the underside of the vehicle, specifically the rear sub-frame and the upper suspension spring mountings. While the MOT indicates structural rigidity is currently maintained, the progression of corrosion in these areas is a known vulnerability for this era of Mercedes-Benz and can become prohibitively expensive to repair if it penetrates the metal. The buyer should inspect the tyre sidewalls for age-related cracking or perishing, regardless of tread depth, and verify that the engine oil and coolant have been changed based on time intervals rather than mileage. A full review of the service history is essential to ensure that the low mileage has not resulted in neglected fluid changes.
