eBay have expanded the “fitment” (That’s wheel nuts, not the edible type!). This allows sellers to show all the cars that are compatible with these accessories in a single listing.
The benefit for buyers is that they’re able to search specifically for products which fit their car. There’s no need to worry if a roof rack comes with the correct fittings to clip onto your car, once it’s listed with parts compatibility if you enter your car details into eBay (or use the eBay Motors app to take a picture of the back of your car) you’ll only be shown products which fit.
For sellers there should be several advantages. Returns should be lowered from buyers who purchase the wrong product by mistake. More importantly they’ll also be able to reduce the total number of listings they manage and pay for to a single listing for each product SKU. When editing your listings to include fitment you should always select your best performing listing (the one with the most recent sales) and relist that product adding fitment from eBay’s .
