2009 Smart (mcc) Fortwo Cabriolet 1.0L Petrol · Y7 OYK

Recurring corrosion on the rear brake pipes and a pattern of tyre degradation are the defining mechanical characteristics of this vehicle, which most recently passed its MOT on 04 September 2026 after a failure regarding the supplementary restraint system warning lamp. The inspection history shows a persistent trend of advisories concerning the rear brake pipes being corroded and covered in grease, a defect that has appeared in various forms across multiple consecutive tests since 2022. While the most recent test resolved the SRS failure, the continued presence of brake pipe corrosion and new advisories regarding a damaged central front lower engine mounting and pitted front brake discs suggest ongoing component wear. The recorded mileage of 28,657 miles over a 17-year period represents a low annual accumulation of approximately 1,686 miles. This usage pattern is consistent with the specific defects noted in the MOT history, particularly the repeated advisories for tyre cracking, perishing, and structural tears, as well as pitted brake discs. Such issues are often associated with vehicles that spend significant periods stationary or are driven infrequently, which can lead to the degradation of rubber components and surface oxidation on metal surfaces that are not regularly cleaned by high-speed driving or heat cycles. A prospective buyer should pay close attention to the braking system and the chassis-to-engine interface. The long-standing advisory for corroded rear brake pipes, which have been noted as being covered in grease, necessitates a physical inspection to ensure the integrity of the lines is not compromised by hidden oxidation. During a test drive, the vehicle should be checked for any changes in brake pedal feel or any pulling when braking, which could indicate uneven pressure or binding. Additionally, the recent advisory regarding the damaged central front lower engine mounting should be investigated; listen for excessive vibrations through the floorpan or a heavy thudding sensation when accelerating or decelerating, as a compromised mounting can affect drivetrain stability. Suspension and tyre condition also require scrutiny based on previous failures and advisories. The history includes reports of worn nearside and offside rear outer suspension arm bushes, so the vehicle should be tested over uneven surfaces to check for knocks or clunks from the rear axle. Given the history of structural tyre failures and sidewall cracking, the current tread depth is less important than the physical condition of the rubber; inspect all tyres for deep cracks or bulging. Finally, the recent advisory for pitted or scored front brake discs suggests that the braking performance should be monitored for any judder through the brake pedal during deceleration.
