2007 Porsche Boxster 2.7L Petrol · FJ57 BHN

A persistent pattern of corrosion on all four brake pipes dominates the MOT record, with advisories appearing on every test from 2020 through 2023 and a failure in 2022 that also highlighted damaged front valve stems and a non‑functional rear parking brake. Although the latest test in November 2025 recorded a clean pass with no defects, the underlying corrosion issue has not been resolved, indicating a chronic risk that could re‑emerge as a safety‑critical fault if left untreated. At 75,388 mi the car averages just under 4,000 mi per annum, a mileage figure that is low for a 2007 model. Such limited annual accumulation suggests the vehicle has seen light use or extended periods of inactivity, which can be benign for wear‑items but may also encourage moisture build‑up in concealed components such as brake pipe fittings and valve stems. The MOT history shows no large gaps in testing, with annual examinations maintained, so the recorded mileage is likely reliable. Prospective buyers should give the brake system close scrutiny. Inspect the exterior of each brake pipe for rust, pitting or signs of leaking fluid, and verify that the pipe ends are free of grease or corrosion that could compromise sealing. During a test drive, listen for any hissing or loss of pressure when the pedal is applied, feel for a spongy or inconsistent pedal feel, and watch for any uneven braking or pull to one side, which could indicate internal pipe degradation or compromised valve stems. The near‑side rear parking brake, flagged as inoperative in 2022, should be tested for proper engagement and release; any slack or failure to hold the vehicle on a slight incline is a red flag. Additionally, the off‑side track‑rod ball joint advisory from 2023 warrants a visual check for excessive play when the steering is rocked and a feel for any knocking over bumps, which would suggest worn bushings. The wiper failure recorded in the 2023 test, where the near‑side blade did not clear the windscreen, should be verified for correct operation and blade condition, as effective visibility is a legal requirement. Given the recurring brake‑pipe advisories and the previous valve‑stem damage, an independent mechanic’s inspection of the entire hydraulic system, including a pressure test and possible replacement of corroded pipes and valve stems, would be prudent before committing to purchase. Addressing these specific items will mitigate the most significant safety concerns highlighted by the MOT history.
