Most of the time having to weld a new quarter panel will be consider total. It's usually a $12,000 job for labor and parts and even some body shops will refuse to deal with it if they don't have the proper equipments to pull the frame straight.
This QP doesn't look too bad, but it will still be a huge PITA to pull it out.
Depending on who you insure with, hit and runs they will repair, but you'll just have to pay the deductible which is usually $150-$500 depending how long you've been using them. If you don't have insurance, you're out of luck and paying to fix that is gonna be a huge headache, unless you want to keep driving like that.
