The base sedan offers power door locks, windows, and mirrors; cruise control; automatic dual-zone climate control; a power driver seat; a tilt and telescoping steering wheel; an AM/FM/CD/XM audio system with auxiliary jack; an air filtration system; and automatic headlamps. Base models also come with "leatherette" vinyl seats, a disappointing fact, but common to most of the European alternatives, too. The Sport Wagon adds a power liftgate to the standard list.
The Performance Package adds the FE2 suspension, 18-inch wheels, and HID headlamps. Opting for the package on the larger V-6 models brings surround sound and a USB/iPod interface, too. A panoramic sunroof, 40-GB hard drive navigation/infotainment system, heated seats, and Bluetooth connectivity are also available. Beware the sticker price, however, as throwing all of these at a CTS can quickly push the price toward $50,000--though even then, it's competitive with the likes of the Audi A4 Avant.
