Someone backed into my car yesterday . Do you think I should get it repaired or is it not that bad to the extent that I can ignore it?

It is a honda civic 2005. Here is a pic of it. http://ift.tt/2tGxdVA was walking back to my car when they were there and apologized. We exchanged insurance info. If I did get it repaired, would their insurance cover everything? The accident happened in a type of parking where it was parallel parked. via /r/cars http://ift.tt/2sXCUBx
