All the press are saying it is a reskinned Sebring, and from the roofline I'd agree.
The platform is still a Chrysler/Mitsu JS.
...but on the plus side, I guess the rework was extensive, including structure and suspension geometries, which means it should act and feel like a totally different car.
I get a kick out of all the camera angles used in ALL the advertising so far. It is like they're trying to avoid taking any direct shots of the roofline.
Having seen one in person, I was kind of bummed... I was hoping the Sebring wouldn't shine through so brightly. It was silver, unfortunately... they do look best in black.
On the topic of the commercial, I dig it. I hope the car does well. I'm just about the only person I know that didn't hate the previous Avenger/Sebring.
