Avenger has a different front end (no grill), different sides (no huge moldings) and a different trunk/taillight combo.
The Avenger front end is swappable with the Sebring's front and they use the same bumper lights and hood (cf hood in the future? lol.. probably not on this car). The trunks/taillights are not swappable however
I am looking at an Avenger/Sebring hybrid front end (with Avenger front end and Sebring fogs) here:

The Avenger and Sebring both came with the same engines... basically like a GMC Sierra and a Chevy Silverado when you're comparing them. Slight differences but same car.
Oh, and thanks for the compliment on the Camry and the Sebring. I sold the Camry for 2 main reasons:
1) The people I was making the payments to were very harsh.. even though I'd gone 2 years without missing a payment)
2) It was a 4 cylinder...
I wanted to see if I could get another loan on it to pay off my at that time current loan and just keep making payments but through a different lender (follow me on this one

) but since it was a 4 cylinder I just didn't put enough effort into it. If you do a search on my username and sift through all the BS you'll find multiple threads where I was asking about a V6 swap... no one seemed like they thought it was worth it... and I agreed. Then, when Rippmods announced they were stopping production of the supercharger for the 4 cylinder, the Camry dream died quickly. While it would have been a while before I would have bought the supercharger, it would have been purchased for the car in order for me to keep it.
