2004 Porsche 911 3.6L Petrol · S300 ADK

The vehicle is currently roadworthy, though the maintenance trend shows a shift toward minor wear-related defects. The most recent test in April 2026 at 119,159 miles passed despite an advisory for central rear brake discs being pitted or scored. This follows a clean record in May 2025 at 114,336 miles, suggesting that while the vehicle remains mechanically sound, components are beginning to reach the end of their service life. At 119,159 miles, this 22-year-old Porsche averages a low annual mileage of approximately 5,416 miles. The data shows a very consistent usage pattern, with roughly 5,500 to 6,500 miles covered between each annual test from 2023 to 2026. This low mileage generally reduces mechanical strain on the drivetrain, but the low frequency of use often leads to degradation of rubber-based components and seals, which aligns with the corrosion issues seen in the history. A buyer must pay close attention to the braking system and under-body protection. The offside rear brake pipe was flagged for corrosion in both 2023 and 2024, indicating a persistent issue that was likely masked by grease or under-body shields. The 2026 advisory on pitted rear discs suggests that the braking hardware is now due for replacement. Furthermore, the presence of undertrays and shields mentioned in 2023 and 2024 requires a physical inspection to ensure structural rust is not hidden behind these components.
