Porsche Boxster / Cayman (987) Common Problems & Reliability

The Porsche 987 generation (2005–2012) is frequently cited by enthusiasts as the "sweet spot" of the brand’s mid-engine history. Retaining the pure, hydraulic steering feel that later models lost, the 987 offered a perfect balance of performance and accessibility in both its open-top (Boxster) and fixed-roof (Cayman) forms. It is positioned as one of the most rewarding driver's cars ever made, though used buyers in the UK must navigate a clear divide in reliability between the "Gen 1" (987.1) and the heavily revised "Gen 2" (987.2) models. Reliability for Gen 1 cars (2005–2008) is dominated by concerns over the IMS bearing and cylinder bore scoring. While the IMS risk is often overstated for cars built after late 2005, bore scoring remains a genuine threat for the 3.4-litre "S" engines, making a professional borescope inspection a non-negotiable step before purchase. The Gen 2 models (2009–2012) solved these issues entirely with the introduction of the 9A1 direct-injection engine, which also brought the superior PDK dual-clutch transmission, though these later cars carry a significant price premium in the UK market. UK-specific checks should focus on the front-mounted radiators and air conditioning condensers, which sit low in the bumper and are prone to rotting due to trapped leaves and road salt. Suspension "coffin arms" and drop links are common wear items that can lead to creaking or knocking on poorly maintained UK roads. For Boxster owners, keeping the rear roof drains clear is essential to prevent water from flooding the cabin and destroying the expensive control modules located under the seats. A Pre-Purchase Inspection (PPI) by a Porsche specialist is highly recommended, as it remains the best way to avoid a "money pit" scenario in this high-performance segment.
