2015 Porsche 911 3.4L Petrol · PY15 NPK

Chronic corrosion of the front brake pipes and recurring windscreen damage have defined this vehicle's recent inspection history, although the clean pass achieved on 15 December 2025 indicates a period of rectification. The trend between 2024 and mid-2025 showed a steady accumulation of advisories concerning the structural integrity of the brake lines and the nearside front coil spring, suggesting a period of mechanical decline that appears to have been addressed prior to the most recent test. Averaging approximately 5,168 miles per year, the recorded mileage is low for a vehicle of this age. This usage profile suggests the car has spent significant time stationary or has been used sparingly, which aligns with the 2022 records of tyre perishing and cracking. Such a pattern often results in the degradation of rubber components and seals due to age rather than wear, as evidenced by the historical tyre advisories. Given the history of corrosion on the front brake pipes and the nearside front coil spring, a physical inspection of the underbody is essential to ensure these components have been replaced rather than simply cleaned or masked. During a test drive, pay close attention to the front suspension for any knocks or unusual vibrations over uneven surfaces, which could indicate a failing coil spring. Check the brake pedal for a firm, consistent response and ensure there is no sponginess that might suggest compromised line integrity. The recurring advisories regarding tyre perishing and edge wear, combined with the previously noted windscreen damage, necessitate a close examination of all rubber seals and glass. Verify that the windscreen has been repaired or replaced to remove the recorded damage. Inspect the current tyre sidewalls for any signs of ozone cracking or uneven wear patterns, particularly on the rear axle, to ensure the vehicle is not suffering from alignment issues or age-related degradation of the tyre compound.
