There are a number of places where consumers can sell Toyota parts, including eBay. According to eBay, some of the best parts to sell online are those that are easy to remove, particularly electronics and high-priced items.
EBay states that consumers should not sell parts that are worth under $20 online, as it is not cost-efficient when shipping is factored in. The site also recommends not selling a part that has not been tested unless it is being sold as-is. If there are many other current listings for the same item, consider holding off on posting the item or selling it locally.
