Oh that totally sucks. Hopefully whatever shop you bring is to will be willing to work with you on the price.
I myself had someone back into my car yesterday who I was in the grocery store and didn’t stick around. I didn’t see it till this morning when I was heading out to run some errands. Went to the body shop today and it’s going to be $3400 to fix. It’s the second time someone has damaged my vehicle in that parking lot. It’s sad that people damage someone’s car and just take off. Either way, karma will catch with them eventually.
