Man! $2700 seems like a damn good deal for the amount of work you got done.At least based on what I've seen others post on here, as well as my experience, though... I think $400 is low. Most people here seem to say $500-600... which is still much cheaper than buying & shipping a new one to you, PLUS having it painted.
Anyway, sorry I don't have the full breakdown available. I had a lot of work done all at once. The front bumper repaired & repainted, the full hood (inside & out) sanded/seams sealed and painted, rear bumper repaired & repainted, and I had some rust starting on the inside bottom seams of all 4 doors that were also sand blasted/sealed/repainted. All of that was only about $2700. The front end repair/repaint was only a fraction of that compared to all the sand blasting & seam sealing that was done elsewhere. I don't know if I can even find the breakdown anymore that I received of costs.... it's been a little while since I had it all done.
So I stopped by 5 other body shops (including GM dealer) and all of them said that it cannot be repaired. They all gave me about the same estimate (approximately $1700 for both the bumper and fender liner). Unsurprisingly, some of them attempted to take advantage of me by adding the cost of a brand new emblem to the estimate or claiming that the deflector needs to be replaced as well. I did find a cheap bumper online at place called Northlake Auto Recyclers for $385 but I do not know how much it'll cost to have it shipped to me, that is if they ship parts at all. I also found another (used) that's only 2 hrs away from where I live so I could actually pick that one up myself but it costs $650 and it is unclear if that's for just the cover or the entire bumper assembly...so I'll have to contact them and see.
This is the one that costs $385.
For now I think I am just going to get a new fender liner since it seems more important than the bumper, especially since the engine bay is starting to get dirty and rusty without the fender covering that area.
