Front Bumper
 

2004 Sebring Sedan Limited with Fog Lights, Satin Jade Pearl (Blue/Sliver)
After cracking my front bumper badly, I will need to replace it.

Looking for the most efficient way in replacing it. Cheapest one I have found on the internet is on discountbodyparts.com $250 for a primered bumper including shipping.

Anybody used this site? Any reccomendations for this project? Are their any bumper kits for these cars, if so how much more should I expect to pay?

How about installation? Will I need to buy mounting kits or anything?

No way to know about damage underneath until you pull off the old bumper cover. Your best bet might be a junkyard part. When shopping, be sure to specify that your car is a sedan. Coupe and convertible parts WILL NOT FIT. They look similar but it's not the same part.
For the finish paint, be sure to deal with a paint shop that is familiar with the original paint spec. That car probably has a triple coat that if not done correctly, will not match and will not look right.

http://www.rockauto.com has bumper covers for less than that by quite a bit. You might want to check http://www.car-part.com/ also. Who knows, you might get lucky and find one in the right color too.
