Some people are a-holes. Sorry to hear.
I've had that happen on a few of my cars in the past right after ownership. Someone keyed it from the front door all the way to the back. One time UPS truck even backed into my car that wasn't even 650miles old.
Anyway about the scratch, is the white primer showing through? If so you will need to paint it. if not, does your nail catch the scratch when to gently rub it? If so that's still probably too deep.
If your nails don't catch, then ScratchX with a foam pad and some elbowgrease should take care of it.
. Do 5-6 apps.
Wax afterwards. Hope that helps.
