2013 Porsche Boxster 3.4L Petrol · J7 NJJ

The vehicle remains roadworthy as of its most recent MOT on 2025-09-03, with a clean pass despite the persistent issue of corroded brake pipes on both front corners. The maintenance trend is not improving — it has remained stable in terms of passing, but the same brake pipe corrosion has recurred across two separate tests, indicating a chronic issue that has not been resolved. This suggests either a failure to address the root cause or a continuing environmental exposure that accelerates corrosion, particularly in areas where grease or debris may have accumulated and trapped moisture. The mileage progression shows a consistent, low annual usage pattern — approximately 2,552 miles per year over 13 years — which aligns with the vehicle’s low total of 33,175 miles. There are no signs of rapid mileage accumulation or long gaps between MOTs, which implies regular, if light, use. The 2021 test at 25,666 miles was clean, and the 2022 test at 29,095 miles flagged the same brake pipe corrosion, suggesting the issue began around that time and has persisted through to the 2025 test. The 2023 and 2024 tests were defect-free, which may indicate temporary mitigation or simply that the corrosion did not yet reach critical levels. A buyer should inspect the brake lines closely, particularly the nearside and offside front pipes, for signs of further corrosion, pinhole leaks, or structural weakening. The recurring nature of this fault implies that the underlying cause — possibly poor sealing, inadequate protection, or a design flaw — has not been corrected. Also examine the suspension components, especially the front bushes and coil springs, which may show signs of wear from prolonged inactivity or infrequent use. Check for any hidden rust in the wheel arches or underbody, as low mileage doesn’t guarantee corrosion-free structural integrity. The brake calipers and discs should be assessed for binding or uneven wear, as the corrosion may have affected fluid flow or mechanical response. Finally, verify that the brake system has been flushed and serviced since the 2025 test, as the presence of grease or debris on the pipes suggests a lack of proper maintenance.
