When messaging people on Facebook or any app or online website always state you want to meet at a police station, if they are sketchy and trying to rob you they won’t reply. Iv even gown as far when someone wanted test drive my car I told them I want to see there ID like a dealership would and never got a response but the where serious up until the point. Watch out a lot of people try to scam and rob for cars online. If anyone is trying to buy your car for more than your asking price but they want you to ship it lmao tell ‘em to fuck off
