2016 Porsche Cayenne 3.0L Diesel · DC66 EUV

The vehicle maintains a technically roadworthy status, though the most recent inspection indicates a shift in maintenance priorities. While the car achieved clean passes between 2022 and 2025 with no recorded defects, the test on 24 April 2026 at 59,226 miles flagged significant issues across all four tyres due to cracking and perishing. This suggests that while mechanical components have remained stable, the rubber components are suffering from age degradation rather than tread wear. The mileage pattern is consistently low for a ten-year-old vehicle, averaging approximately 5,900 miles per year. Between the 2022 test at 52,408 miles and the 2026 test at 59,226 miles, the car covered only 6,818 miles. This low-frequency usage typically results in less wear on the drivetrain and engine components, but the recent failure on the sidewalls confirms the suspicion that the vehicle may have sat stationary for extended periods, leading to dry rot and material failure. A buyer must prioritise a thorough physical inspection of the tyre set, as the 2026 advisory indicates an immediate need for replacement. Given the low mileage, the buyer should also scrutinise the suspension bushings and rubber arms for cracking, as these often perish on vehicles that are not driven regularly. The MOT record shows no history of structural corrosion or brake failures over the last five years, but the lack of defects in previous years does not rule out age-related degradation of fluid-based components or seals.
