Kuan, first check your policy and if SF is the other driver's policy, ask for a copy of the binder. What does that lovely ISO standard language say about the quality and nature of repairs? The policy may limit the type of repair and may also authorize the use of "OEM quality" vs. OEM parts.

Second, either web search or contact your state's insurance commissioner's or other regulatory agency to see if your state has specific regulations about repair claims. Different states have different standards. Some allow CAPA parts, some don't, some have provisions for reduction in value, etc.

Do get estimates from quality independent shops.

The other option is to have your carrier do the repair, then have them institute a subrogation action against SF via inter-company binding arb.
