Even though we have not allowed threads replies to classified ads for years, we still get lots of questions about it. So, I thought a tutorial was in order. Let's say you found a car that you want to buy and you need to get a hold of the owner to offer some ridiculously low sum for his vehicle. Easy. 1. Click on the user's username located right under the avatar. That will bring you to a pop up. 2. On the pop up window, click "start a conversation." From there, you can have a private conversation with the user that placed the ad. A more thorough tutorial of this with pictures is available here: http://www.jalopyjournal.com/forum/threads/how-to-respond-to-a-classified-ad.923510/ ALSO; The App most of the time doesn't work for the classifieds. Use your Browser or a PC.
