I had my 07 X5 in a similar situation with pregnant wife sitting at red traffic light, guy hit her from back lightly causing lower tailgate damage as yours bumper in tact but had a faint line running on top of bumper. I just put it in the shop, the lower tailgate was around $600. Bumper also has to be replaced since when they took the bumper off 4 clips were broken which are a part of the bumper. Mind you, i dont have the newer bumper so no paint work needed. Also diminished value I asked for had no luck so just left that argument.

Good luck.
