Core Charge. Core is an acronym for ‘Cash On Return’. A core charge is sometimes applied to rebuildable parts such as engines or alternators that can be redeemed for a portion of their original price. If the part you are purchasing has a core charge applied, it will be noted in the description.

Parts Grading. A standard code system is used to communicate the condition and quality of a part between automotive recyclers, automotive repair shops, and insurers. Knowing how these codes are used will help you understand whether the part meets your expectations before you buy it and what you can expect from the part when you receive it.
