SCAM Help??

When I was selling my 2004 BMW in 2020 I listed on FB Marketplace. Had several real potential buyers (one an arrogant low baller who got pissed when I told him anything below a certain amount I'd just keep it as I really didn't need to sell). So, after a couple of weeks I threw it on CL. Nothing but scammers, so one day I edited the ad to ask any real person who read the ad to contact me, interested in the car or not. One guy did just that. I have no problem like this with anything else I put on CL, but cars are something else.

The buyer ended up coming at me through FB...
