2001 Porsche Boxster 2.7L Petrol · S5 RWF

A chronic and unresolved concern regarding brake line degradation dominates this vehicle's mechanical profile, with all four corners consistently flagged for corroded brake pipes covered in grease or other material across five consecutive annual inspections. While the vehicle successfully passed its latest MOT test on 17 July 2026, this long-standing advisory trend indicates a persistent risk that has been repeatedly bypassed rather than permanently rectified. The application of grease or protective coating often masks the true extent of the corrosion, meaning the structural integrity of these critical hydraulic lines remains a significant, unquantified hazard that requires immediate professional assessment. With a recorded mileage of 59,937 miles over approximately 25 years of service, this Porsche has averaged a highly conservative 2,397 miles per year. While low mileage is often seen as desirable, in a performance vehicle of this vintage, such limited usage typically points to extended periods of inactivity. This pattern of sparse operation can lead to its own mechanical complications, particularly the drying out of engine seals, degradation of rubber suspension bushes, and internal condensation within the engine and exhaust system due to a lack of regular, full-operating-temperature heat cycles. A prospective buyer must prioritise a physical inspection of the brake lines on a vehicle lift; the grease or protective material must be cleaned back to determine whether the metal pipes require complete replacement, which is a labour-intensive job on this mid-engined platform. Additionally, the latest test highlighted that the nearside rear inner tyre is worn close to the legal limit and worn on its edge. This specific wear pattern strongly suggests a wheel alignment issue or worn rear suspension geometry components, such as control arm bushes or track control links. During a test drive, the buyer should pay close attention to any tendency for the rear end to wander or feel unstable under cornering, and listen for knocking noises when travelling over uneven road surfaces. Although not flagged in the two most recent tests, an oil leak was noted as an advisory in both 2022 and 2023. On a water-cooled Porsche engine of this era, oil misting or weeping is a common issue that can originate from the rear main seal or spark plug tubes. A thorough inspection of the underside, particularly around the engine-to-gearbox bell housing interface, is essential to ensure this leak has not worsened. During the test drive, monitor the oil pressure, check for any burning smells after the engine reaches operating temperature, and inspect the ground beneath the vehicle after it has been parked to confirm whether active fluid loss is occurring.
