I backed iinto a tree and the back of car needs to pounded out. on 2008 Mercury Milan

I backed into a huge tree (probably at about 10 mph) which resulted in screwing up the alignment of the trunk and the tail lights. It's not really visible if I don't point it out, but it's bad. There's a dent by the gas tank, as well. It's basically like I crunched the back in. It knocked off the license plate. That's about it. Thanks so much. Paula Baker (new driver).

Sorry Paula, unless someone here happens to do body work also, this is a mechanical repair site.
