Just realized this after trying to find my listing by searching for it like a typical buyer would. If you choose the make, model and used, it will be there. But if you further refine it by a range of years, my listing disappears. As an experiment I tried the same process on other cars and found 2 more with the same issue in just a few minutes. It primarily occurs on auction format listings. I can add details if anybody is interested, but I contacted Ebay support and they finally saw the issue but don't know when it might be fixed.
