2006 Mercedes-Benz CLS 3.5L Petrol · JR02 ABC

The most recent MOT inspection on 23 February 2026 resulted in a pass, but the vehicle shows a concerning trend regarding steering and braking system integrity. While the car has passed its tests consistently over the last several years, the recurrence of advisories suggests a pattern of progressive wear rather than a strictly preventative maintenance regime. Specifically, the steering rack inner joints have been flagged as an advisory for two consecutive years, indicating that this component is deteriorating. Furthermore, the presence of corroded rear brake pipes, which were noted to be covered in grease or other substances, suggests an attempt to mask corrosion rather than a permanent repair. This combination of recurring steering issues and obscured brake line degradation indicates that while the vehicle is currently roadworthy, it is entering a phase of more significant, costly mechanical repairs. With a recorded mileage of 154,452 over approximately twenty years, the vehicle has covered an average of roughly 7,723 miles per year. This represents a relatively low-to-moderate annual usage profile, which is typical for a premium executive saloon of this era. While lower mileage generally implies less wear on the engine and drivetrain, it can often lead to other age-related issues. In this specific case, the mileage is consistent with the observed degradation of rubber components and the onset of corrosion. The lack of rapid mileage accumulation means the mechanical components have not been subjected to high-frequency stress, but the vehicle has likely spent significant time in environments where moisture and road salt could contribute to the underbody rust and brake pipe corrosion noted in the historical records. A prospective buyer must pay close attention to the steering and suspension during a test drive. The advisory for play in the steering rack inner joints is a significant concern; you should listen for knocking or clunking sounds when turning the wheel at low speeds or when driving over uneven road surfaces. If the steering feels vague, imprecise, or wanders on the motorway, the rack or its joints may require immediate replacement. Additionally, the previous advisory regarding an oil leak, while described as not excessive, warrants a thorough inspection of the engine bay and undercarriage for fresh seepage. You should check for any signs of weeping from the rocker cover, oil filter housing, or sump to ensure the leak has not worsened since the 2024 inspection. Regarding the braking system and chassis, the history of corroded rear brake pipes is a high-priority item. During your inspection, verify that the brake lines are not just covered in grease but are structurally sound and free from heavy scaling. During the test drive, monitor for any pedal sponginess or a change in brake feel, which could indicate fluid ingress or compromised lines. You should also inspect the underbody for the progression of the rust mentioned in 2021 to ensure it has not compromised the structural integrity of the chassis. Finally, given the age and the intermittent nature of the usage, check the condition of all rubber bushes and suspension arms, as the 2020 records show a history of wear in the nearside front suspension components that may have recurred elsewhere.
