Brakes squeak, shrilly and obnoxiously. Porsche says there are no plans to install softer brake pads for tender U.S. sensibilities, so either get over it or use the brakes enough to heat them. Warm brakes don't make the noise, cold brakes do. Torque, though much enhanced, could be better just off idle. Those unfamiliar with sports cars will find themselves killing the engine once in an inattentive while, trying to start from rest.
Storage space is tight.
The air bags take up the glove compartment space. Porsche tries to compensate with door pockets, console openings and a nook in the bulkhead behind the seats. But it doesn't take much baggage to use up the slots. And there's no cup holder. If you want to sip, stop at a roadside cafe.
