Insurance will total it, but I fixed quite similar damage on my dads W124 when he had a low speed encounter with a Hyundai Accent.

Looks like the damage is pretty much contained to the hood, fender, bumper, and headlight. Unless the airbag got deployed, I would grab some parts from a junk yard and fix it.
