2006 Porsche Cayman S 3.4L Petrol · A13 PBY

The vehicle most recently passed its DVSA MOT test on 17 September 2025 with no defects or advisories recorded, indicating a clean roadworthiness outcome at the time of examination. Looking back over the four most recent test cycles, the Porsche Cayman S has demonstrated a consistently stable maintenance profile, passing on each occasion from 2022 through 2025 without any advisories or failures appearing on the record. This unbroken sequence of clean tests suggests that the vehicle has been kept in good mechanical order and that any remedial work required at the time of testing has been addressed promptly. A completely clean advisory record across multiple years is a positive indicator, although it is worth noting that MOT testing represents only a baseline safety and emissions check and does not necessarily reflect the condition of higher-mileage service items such as the timing chain, intermediate shaft bearing, or IMS retrofit status, which are particularly relevant to this generation of flat-six Porsche powerplant. The recorded mileage of 82,194 miles against a 2006 manufacture date equates to an average annual accumulation of roughly 4,100 miles, which is notably low for a twenty-year-old performance vehicle and points towards predominantly light or recreational use, with potential extended periods of standing. Such low usage patterns can be beneficial in terms of avoiding wear on major drivetrain components, but they introduce their own concerns around calendar-based degradation of fluids, seals, and rubber components. Significant standing periods can lead to drying and cracking of suspension bushes, oxidisation of brake components, and flat-spotting or sidewall perishing of tyres, as well as sulphur accumulation within the engine oil and degradation of the coolant and brake fluid irrespective of mileage covered. Given the clean MOT record but low annual mileage, a prospective buyer should prioritise a thorough physical inspection beyond what the test certificate reveals. Begin with a careful examination of all four tyres, checking the sidewalls for cracking or perishing consistent with age rather than tread wear, and verify that none of the tyres are of a mixed brand, size, or age grouping, as prolonged standing can mask underlying wheel alignment or suspension geometry issues. Inspect the brake discs for severe surface corrosion or pitting, particularly on the inner faces, and confirm that the calipers are not seized or binding by ensuring the vehicle rolls freely on a level surface; binding calipers from infrequent use are a common issue on low-mileage cars and can lead to uneven pad wear and localised disc overheating. Additionally, check the condition of the brake and clutch hydraulic fluid, which degrades over time due to moisture absorption, and request evidence of recent brake fluid replacement regardless of the MOT outcome. Further inspection should focus on the condition of the 12-volt battery, as vehicles of this age and low usage profile are highly susceptible to battery degradation from parasitic drain during standing periods, often resulting in repeated jump-start requirements or intermittent electronic faults. Verify that the engine starts promptly from cold without excessive cranking, that all dashboard warning lamps extinguish correctly, and that the cooling fans operate as expected. Examine the underside of the vehicle and engine bay for any evidence of coolant or oil weeping from ageing seals and gaskets, and check the exhaust system for corrosion, particularly at mounting points and joint flanges where standing moisture can accelerate rusting. Given the known concerns with intermediate shaft bearing failure and rear main seal oil leaks on the 9A1 flat-six engine in this model, it would be prudent to have a specialist Porsche technician perform a compression test, borescope inspection, and oil sampling to confirm internal engine health, as these issues may not be reflected in MOT data but represent significant rectification costs if present. Finally, ensure that the service book is fully stamped and that the timing chain, spark plugs, and drive belts have been replaced at the manufacturer-recommended intervals, as these time-sensitive items remain critical regardless of the low recorded mileage.
