When listing auto parts on eBay it is critical that you include all available fitment data. Otherwise many of your potential customers will never see your product - even if it is exactly what they are looking for and at a price they are willing to pay. Fitment data that has been properly added to your listing will help your customers quickly determine if the part is compatible with their vehicle make, model, and year. Many shoppers that are looking for a specific part will start looking by filtering their search by the vehicle that needs the part. If you haven’t included fitment information then those shoppers will never see what you have to offer. Some of the remaining shoppers might find and buy from you, only to return the part later when they find out it doesn’t fit their specific vehicle and needs.
