Safest way to sell a car private party?

This might sound like stupid question but how do Houston residents typically sell a car on the private market and it not be a nightmare? I've already had one car of mine stolen since moving here and have heard all sorts of horror stories meeting up to let people test drive. Obviously meeting in a safe place might help a bit but I'm honestly not so sure. I'm going to require a copy or take a photo of their ID and insurance before a test drive but looking for any other tips I might be overlooking.
