First off, it you left valid contact information, you WILL NOT be charged with hit & run. Technically, they don't have a claim against your insurance company. They have a claim against YOU, that your insurance company is bound by contract to handle for you.
Without knowing the year, make and model of the damaged vehicle, and the part that was actually damaged, we can't really make a BAD guess. Even with complete details, we can only GUESS what labor rates for repairing paint are. You say "It's probably less than a square foot of scratches" Translation: The ENTIRE panel will need refinished.
Normally you are looking at about $500 for a minor area to repair. And at the most about $2000. Now all of this will depend on a few things like what kind of a car it was.
And lets say that if it was a nice german car well then sistah you looking at the bigger #. And weather if there is more then just a scratch normally there is a dent that may need to be pulled out or something like molding / trim or lights so the cost will go up . But minimum is $500.
Sorry for the bad news. And I hope that its minimal.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
