What is not reasonable is her sister demanding she also cover the remaining fines and interest, threatening to “retrieve the money any way she wants,” and apparently already stealing packages as a preview of what that means. This is not a billing dispute anymore. It is coercion.
The guilt about the dent is the most human part of this story. She bought equipment to fix it. Her sister shipped the car before she could. At some point personal accountability has to meet basic fairness, and fairness here is pretty clear: you pay for what you actually did, not for what someone else did in a car they took back and kept driving.
She owes one fine, fine. She does not owe the rest.
