Without an actual picture and the ambiguous verbage used, here's your otionsoptions:
- most often, minor crashes do not damage the bumper itself but the "clips" that hold it on. With the proper tools, you can remove your bumper cover, replace any damaged "clips" and then reinstall the bumper cover
- if the cover itself is cracked, your quote listed it the part as $370. You may find a cheaper alternative at aftermarket places, and even cheaper would be the junkyard. Aftermarket places usually have unpainted bumper covers, while the junkyard should have a bumper cover in good shape that is already your colour. If you need to paint, you are probably looking at $30-$50 in spray cans, then you install your new cover yourself.
