Chrysler Sebring

Chrysler has shown pictures of the 2007 Sebring, a mid-sized sedan that will enter production in America later this year. New from the ground up, the dynamic exterior borrows cues from the Crossfire in the front three-quarter, while a part-masked C-pillar helps accentuate the Sebring's arched cab, eschewing the 'chopped' look of the larger 300C.
