Parts compatibility
Over time, eBay has developed a comprehensive vehicle parts & accessories catalog, containing over 1.2m vehicle parts & accessories. Parts compatibility, also known as fitment, enables sellers in most vehicle parts & accessories categories to link their listings to eBay's catalog; improving the listing, buying, and selling experience by displaying all vehicles that their product is compatible with - Although the program is not mandatory, sellers who do adopt eBay's catalog data for their listings tend to see significantly higher sales than those that do not.
