Exterior:
The Porsche 987 Cayman exhibits vulnerability in its headlights, susceptible to stone chips and cracks. While light scratches can be polished out, replacing a damaged light can be a costly affair, ranging from hundreds to over $1000. Owners often recommend opting for the Bi-xenon headlights if a replacement becomes necessary. Yellowing or fading of headlights is a common issue, but easily remedied with numerous online tutorials.
The climate condensers and radiators, positioned low in the front, are prone to corrosion, stone chips, and potential leaks. The front lower intakes can accumulate debris, necessitating a thorough air-con test during a pre-purchase inspection to avoid costly component replacements.
Gas struts holding the bonnet open may show signs of wear but are relatively inexpensive to replace. Tailgate rattling can occur due to misaligned hinges or worn seals, usually not a cause for concern unless indicating poor repairs post-accident.
Any signs of rust on a Cayman should raise red flags, suggesting potential issues with accident repairs.
Interior:
Headliner issues often arise, with the roof fabric delaminating and falling in.
Cable wear on door handles is common, leading to handles sticking out.
Interior plastics may experience brittleness, cracking, or peeling surface finishes.
Water ingress can cause complications, often from blocked drainage holes or faulty rubber seals. These demand close inspection, especially behind the front seats.
For the Boxster variant, ensuring the roof mechanism works flawlessly and checking for leaks, possibly by simulating rain, is crucial.
Owners have reported various issues with cup holders, but most are easily fixable with online tutorials.
The air conditioning blend door foam can disintegrate, affecting climate control over time and blowing foam debris into the cabin.

Mechanically:
Addressing the notorious IMS (intermediate shaft bearing) issue, early models faced potential failures causing catastrophic engine damage. However, ignoring the hysteria often found online, only a very small percentage of the early 987s actually fail due to this and if the IMS was replaced and upgraded as a preventative maintenance measure (which many are) it’s unlikely to be an issue. Preventative maintenance measures, frequent oil changes, and occasional spirited driving, the theory being that the bearing is lubricated more substantially at higher engine RPM, can all mitigate risks.
Bore scoring issues, causing excessive oil consumption, again primarily affected earlier models. However, this needs to be investigated by a specialist prior to purchase.
Oil leaks, often from the rear main seal and spark plug tubes, are common in aging Porsches like the 987.
Issues with the AOS (Air Oil Separator) can produce smoke on start-up but are relatively inexpensive to fix. Coolant leaks, particularly from the expansion tank and water pumps, are prevalent, require attention. Brakes and suspension components, such as lower control arm bushes, are worn items needing replacement every 40-60k kilometres.
Servicing and repair costs are comparatively high not only because it’s a Porsche but often due to challenging access to engine components.
Manual transmissions are generally reliable, though selector cables can break. Not a difficult or expensive repair.
Pre-update Tip-tronic gearboxes are solid but lack the fun factor of PDK, which, while not unreliable, incurs high repair costs if or when issues arise.
Before paying a premium for genuine Porsche components, the 987 Cayman benefits from a robust aftermarket parts market and abundant DIY resources, making it an excellent platform for enthusiasts, even those on a tighter budget.
In summary, the 987 Cayman falls into two categories: meticulously maintained examples owned by passionate and financial enthusiasts, likely to be very reliable, and neglected ones owned by those possibly not in the financial position to afford a Porsche, therefore cutting corners, causing significant headaches for the unprepared future owners.
