As with any Porsche, the 2012 Boxster has a long list of available upgrade options, many of them a la carte, some wrapped into common packages, but the base spec is fairly comprehensive, perhaps even too comprehensive for some purists--though that's what the Spyder is for.
All Boxsters get air conditioning, CD/AM/FM stereo, leather-trimmed seats, alloy wheels, power doors/locks/mirrors, a power-folding soft top, keyless entry, Bluetooth connectivity, and a universal audio interface. The Spyder does away with the daytime running lights, air conditioner, stereo, and replaces the power roof with a manual unit.
Mechanical and appearance options include the excellent PDK transmission, sport seats, larger wheels and tires, and a set of packages that bundle in design, technology, and performance elements--they're so in-depth and varied you'll likely have to spend some time with the order book before pulling the trigger. The Sport Chrono option, which enhances the sport tuning of the car and adds some unique design elements, is a particularly attractive package, however.
