I replaced the front bumper cover on my car, not that hard to do. There are two plastic screws on the bottom of the bumper, remove these, then remove the turn signal lights, there are screws behind there. then you work around plastic water guards around the bottom of the bumper cover. Remove the clips that attach the two together Then lastly you have to remove the headlights to access the bolts that secure the bumper cover to the actual bumper. then you are home free! I would recommend that you get some new clips for reattaching the water guard to your new bumper, also don't forget to remove the license plate bolts that are wedged into the inside of the bumper.
If you haven't ordered the replacement already, I would recommend D and H auto in Naperville IL, I got mine from these guys and they will even paint it for you, just give them your VIN, mine was FLAWLESS good luck!!!!!
