2006 Porsche Cayman 3.4L Petrol · F4 ETT

The vehicle is currently roadworthy, but the maintenance trend indicates a shift toward reactive rather than proactive upkeep. In the most recent test in October 2025 at 71,440 miles, the car failed due to significantly worn rear brake discs, a worn offside front anti-roll bar linkage ball joint, and a noisy exhaust. While it passed just five days later at 71,452 miles, the persistence of the noisy exhaust advisory suggests this specific issue was not fully rectified during the immediate repair process. The mileage profile is exceptionally low for a twenty-year-old vehicle, averaging approximately 3,500 miles per year. There is a notable gap in usage data between May 2023 and October 2024, where the car covered 17,691 miles in just seventeen months. This rapid burst of activity follows a period of only 1,543 miles recorded between 2021 and 2023. Such intermittent usage patterns often lead to the degradation of rubber components and seals, which may coincide with the mechanical failures observed in the higher-mileage tests. A buyer must conduct a close physical inspection of the suspension geometry, as the failure of the anti-roll bar linkage indicates that ball joints are reaching the end of life. The previous failure of the rear brake discs warrants a check for seized calipers or uneven binding, which could have caused the accelerated disc wear. Additionally, the recurring noisy exhaust requires a thorough check for manifold leaks or perished mounting brackets that are common on vehicles that sit for extended periods. Given the history of uneven tyre wear in 2024, the wheel alignment should also be verified to ensure the suspension is not causing premature tyre scrub.
