Comfort isn't always a first consideration with a sports car, but the Cayman is acceptable for its level of performance. The ride can still be occasionally jarring on rough roads, and road noise can become tiresome on coarser surfaces, but overall the interior is comfortable. Despite somewhat narrow standard seats, they don't offer much side support, so enthusiastic drivers or those who spend much time on the track will want to opt for the adaptive sport seats with their power-adjustable bolsters.
The 2010 Porsche Cayman is a two-seater with a cabin that Cars.com says is "definitely on the cozy side," but "not the least bit cramped." Even though there's enough room, the standard seats "lack long-distance lumbar firmness," according to ConsumerGuide. Edmunds, on the other hand, finds the "seating is comfortable" but calls legroom simply "OK." Cars.com does find the sport seats "plenty capable of holding you in place during aggressive driving," but notes "some soreness" after long stints in the seats. Upgrading to the adaptive sport seats cures these ills, however, as ConsumerGuide notes, thanks to adjustable side bolsters and memory settings.
Without the need to stow a top and with a bit more room behind the passenger area thanks to a hatchback design, the 2010 Porsche Cayman offers slightly more cargo practicality than the Boxster. Due to its mid-mounted engine, the Cayman can stow gear both in front and in back. Interior cargo space is lacking, but this is a compact two-seat sports car, after all. If you want six cup holders, consider the Cayenne.
Kelley Blue Book predictably calls Porsche out for the "dismal cupholders" inside the Cayman, but tempers that by pointing out "stowage space under both the front hood and beneath the rear hatch" are good. The Cayman compares well to the Boxster, however, as its "hatchback body style offers more cargo capacity," says Edmunds. ConsumerGuide likes the "cargo bays front and rear for more luggage-carrying possibilities than in many two-seaters," but again bemoans what it calls "little in-cabin storage space."
Materials and build quality are, as usual from Porsche, top-notch. Kelley Blue Book finds the Cayman's interior materials "well-finished," with "lots of leather and brushed aluminum accent trim." ConsumerGuide raves over the "rich-feeling, carefully assembled cabin materials" but doesn't like how Porsche charges extra "for amenities some rivals include as standard, including full leather upholstery." Cars.com also considers the interior impressive, noting the "mostly nice materials throughout and fine build quality" throughout the cabin of the 2010 Porsche Cayman.
Unfortunately, good materials and high build quality don't necessarily translate into a quiet ride, as is the one weak link with the cabin of the 2010 Porsche Cayman. ConsumerGuide notes that "the engine's location behind the seats means more mechanical ruckus than in front-engine designs," a problem that is only made worse by what Autoblog calls "minimal sound insulation."
