Cheers guys for all replies, been out to look i think its just a case of getting some help, prob a body shop, to clip it all back together. I've taken some pics which i will put up later.
Bumper isn't cracked, slight crack in the undertray plastic but id say max 2 inches. I can live with a 2 inch crack lol
How would i tell if the bumper bar is damaged though, a mentioned that might be expensive. Is it visible or well hidden under all the trim pieces?
