* Your insurance coverage: If you have comprehensive car insurance, this usually covers damage from vandalism. However, you'll likely have a deductible to pay before the insurance company covers the rest. Liability insurance only covers damage *you* cause to others; it won't cover vandalism to your own vehicle.
* Identification of the vandal: If you know who vandalized your car and can prove it, you can sue them in civil court to recover the costs of repairs. This can be difficult and expensive, and there's no guarantee you'll recover all your costs.
* Security footage or witnesses: Evidence can be crucial in identifying the vandal and pursuing legal action.
* Location: The location of the vandalism might influence who's responsible (e.g., if it happened on someone else's property, their homeowner's or renter's insurance *might* be involved, depending on their policy and the circumstances).
In short, your comprehensive car insurance is the most likely source of payment for the repairs, but you'll need to file a claim and may have a deductible. If you have no insurance or insufficient coverage, you'll be responsible for the repair costs yourself, although you might try to recover costs from the vandal if you can identify and prove their guilt.
