Selling cars

At first the original post was on Marketplace for a 2005 Nissan Maxima SL four-door sedan for $1,200. When I asked about it through Messenger the name on it was Tekle. That person told me they were selling it for their aunt and I needed to contact her through email. When I did she said she was selling it because her son died in a motorcycle accident 4 months ago and the car has bad memories. The method of payment was to be through eBay Motors. The aunts name was Olga Davis. The first red flag was that not even an hour later I looked on Marketplace again and it was gone. The second red flag was the fact that they would not answer any questions I had and was obviously an automated response. Next was the location on Marketplace was Dayton Ohio but the location when they emailed me back with the so-called Buyer's Protection ID number that was actually in Alabama. Also they did send me what looked like a legitimate ID number and information from eBay but when you clicked on certain things you were not able to so it was clearly screenshots.
