it's held on by 5 plastic clips. you can use a flat head screw driver and wedge it in there and the snaps should come out. but be carefull, i was very carefull and i still broke two of them since the car is 10 years old and they are cheap plastic.
The car w/ that custom grill that you are looking at on G20Style.com, I'm pretty sure it belongs to a guy named Elroy. He's on teammeguiars.com for the show contest on that site. I know that he was talking to me about selling his full kit and you can reach him at [email protected]
