2008 Porsche Cayman 3.4L Petrol · AJ57 CJF

The 2008 Porsche Cayman presents a stable and improving maintenance trend, culminating in a clean pass on 3 February 2025 at 16,999 miles with zero defects recorded. That result marks a clear step forward from earlier years, where tyre condition advisories appeared at consecutive tests. The most recent certificate, now over sixteen months old as of June 2026, confirms the vehicle met all roadworthiness standards at the time, though a fresh test would be prudent given the age of the current MOT. The mileage profile tells a story of exceptionally low use. Across roughly eighteen years the Cayman has covered 16,999 miles, averaging approximately 944 miles per year. The annual increments are modest and consistent: 859 miles between the December 2020 and December 2021 tests, 213 miles between December 2021 and January 2023, 139 miles between January 2023 and February 2024, and 859 miles between February 2024 and February 2025. That pattern suggests short, infrequent journeys rather than sustained daily commuting. Prolonged periods of standing can cause flat-spotting on tyres, stale fuel, moisture accumulation in brake fluid and the exhaust system, and localised corrosion on brake discs and suspension components that would not appear on a low-mileage vehicle used regularly. The recurring theme across the MOT record is tyre deterioration rather than structural or mechanical failure. In the 21 December 2021 test at 15,788 miles, both front tyres were flagged for slight perishing within the tread. The same pair reappeared as advisories in the 30 January 2023 test at 16,001 miles, described as cracking or perishing. That the front tyres needed replacement before the February 2024 test suggests the owner eventually addressed the issue, and the subsequent two passes were clean. A buyer should still inspect all four tyres carefully, checking the date stamps, sidewall condition, and tread depth, as rubber degrades with age regardless of mileage. Given the low annual use, the spare tyre, if original, will almost certainly be perished and should be examined or replaced. Beyond tyres, the Cayman's mechanical components deserve close scrutiny. Low-mileage Porsches that stand for long intervals often develop sticking rear calipers, corroded brake discs, perished suspension bushes, and weeping seals. The underside should be inspected for structural corrosion, particularly around the front and rear suspension pickup points, sills, and the battery tray area known to trap moisture on this model. Suspension bushes, drop links, and anti-roll bar links should be checked for deterioration, as age-related degradation can occur even without significant mileage. A pre-purchase inspection with a Porsche specialist, including a brake fluid moisture test and a thorough underbody examination, would provide the clearest picture of the vehicle's true mechanical condition.
