We have recently undergone many changes to the organization of the marketplace during the transition to a tag-based marketplace. Why the change? Read about it here: Link
If you are looking for something specific, you can do a quick search in the search bar. If you are just browsing, clicking on the 'Porsche' tile on the homepage will take you to: https://www.panjo.com/tags/porsche. This page displays all of the listings created with a 'Porsche' tag. Our community team actively monitors new listings to make sure they have appropriate tags.
In both scenarios, Panjo automatically recommends popular tags related to searches you make. In a few weeks, we'll be working on deeper search tools (e.g. filtering results by tag) and improving overall search on Panjo.
Hope this clears up any confusion. Let me know if you have further questions!
