We had ours done a few years ago. I want to say it was $900ish. That was for a whole new bumper. Pretty much any damage and they just replace the whole thing. Sorry.
It really depends on how bad the damage is. It could be just scratches that they can buff out or they may have to replace the bumper and reinforcement behind it. I've seen a 'new bumper' range from $400-$1700
If it's minor damage, you are looking at plastic bumper cover, possibly the foam absorber that's behind that, maybe a few plastic clips, and paint. Somewhere in the $500 range. $250 in parts and $250 for labor.
We had the rear bumper cover replaced and painted on our Elantra a few months ago. Insurance paid $424. Body shop did the work for that amount so there was definitely some profit in it for them even at that price. We took it to our dealership's body shop because I did not want aftermarket parts used.
We're taking it in this morning - thanks for the responses. I'll f/u to let you know the price. Eta. About $800 for a bumper replacement if there's no other damage. But he said there may be damage behind the bumper ugh.
