I wouldn’t worry too much about a proper fix, especially if the dealer is doing it. I’ve fixed a lot of deer strikes. In fact I have one in my shop right now, and another waiting outside for it to be finished. Usually there is no big thing to fixing them.
I don’t recognize your license tag, or know who you are insured by, but many insurance companies treat deer strikes as a comprehensive claim rather than a collision claim. I guess they figure that deer stupidity is an act of God. The nice thing is that a comp claim will usually not raise your rates. You may also have a lower deductible on your comp coverage. Lots of folks do as comp is cheaper to buy than collision.
