How it works
A repair estimate may use OEM, recycled, remanufactured, or aftermarket parts depending on policy language, state rules, availability, and repair needs.
Example
A damaged bumper estimate specifies a new manufacturer-branded replacement rather than a part made by another company.
Why it matters
Part type can affect price, availability, fit, warranty, and what you pay if you request an upgrade.
What to check on your policy
Read the parts provision, ask the shop to identify every proposed part, and request an explanation of any price difference you must pay.
