2009 Porsche Cayman 3.4L Petrol · T44 ERC

The 2009 Porsche Cayman currently holds a valid MOT certificate following a pass in February 2026 at 63,044 miles. The overall maintenance trend remains stable, though the most recent inspection introduced a specific corrosion concern. The tester noted the offside rear brake pipe is corroded and covered in grease or other material. This requires immediate physical verification to determine if the corrosion is superficial or if it compromises the structural integrity of the hydraulic braking system. Averaging roughly 3,700 miles per year over its seventeen-year lifespan, this vehicle has experienced exceptionally low usage. The mileage progression is consistent, showing a steady increase of approximately 3,000 to 5,000 miles between annual tests from 2022 to 2026. Such low annual mileage often indicates light weekend use or extended periods of static storage. While this preserves the drivetrain, prolonged standing accelerates the degradation of rubber components, which directly aligns with the widespread tyre perishing observed across all four wheels during the March 2025 test. A prospective buyer must prioritize a thorough undercarriage inspection before purchase. The March 2025 test recorded all four tyres as slightly damaged, cracking, or perishing, strongly suggesting the vehicle sat idle for long durations without regular rotation or replacement. You should verify that these tyres have been replaced since that date. The grease-covered corroded brake pipe flagged in 2026 also demands close examination. Inspect the entire brake line routing for active flaking, moisture retention, or weakness, particularly around the rear axle and suspension mounting points. Ensure no binding calipers or uneven brake disc wear are present, as infrequent driving frequently leads to seized components.
