That said, the base seats are comfortable if a bit under-bolstered for spirited driving. The adaptive sport seats improve on that, but at the expense of potentially distracting inflating/deflating during cornering. Both sets of seats are well-suited to long drives, provided you can deal with the Cayman's other minor faults.
Headroom isn't one of those faults, however, with the arched roof providing plenty of cranial space. Cargo room is surprisingly good, too, as long as you don't have particularly large packages to stow: there's space behind the mid-mounted engine and in the front trunk. Porsche even offers a fitted luggage set to make the most of every available cubic inch.
Storage in the cabin isn't fantastic, but there is room for small items in the center console. Build quality throughout the cabin is top-flight, as are materials for the most part; a few interior plastic pieces don't quite live up to the standard set by the rest of the space.
