That's too bad. Right before christmas, Someone backed into my XF. Luckily they only skinned the paint from bumper. During the inspection, the adjustor found a couple of broken clips on the grill. He added a new grill to the repairs (just to be nice). Well, the Chrysler body shop said there were no new grills or used grills in the United States. Needless to say, I didn't get a new grill, just repaired clips.
I hope you have better luck getting parts.
