Upgrading your Sebring depends greatly on the model you start with. For example, base model Sebrings are stuck with the 2.4-liter four cylinder, while the other trims offer significant upgrades throughout. Inside, base shoppers can option up to a six-disc CD/DVD/MP3 stereo, Sirius Satellite, hands-free communication, heated cloth seats, daytime running lights, a sunroof and a Convenience Package that includes alarm, travel computer, information center, express down windows, YES Essentials seat fabric and remote start. New features such as a heated and cooled cupholder and MyGIG, Chrysler’s 20-gig infotainment system, are only available on Touring and Limited models.
