You sound really familiar with the process :thinking-face::thinking-face::thinking-face:
I didn't really have any crazy scam attempts (that I know of) but when I sold my Silverado mid 2020 when COVID spiked used truck prices to crazy levels, I had something like 30 messages overnight, trying to buy it. Offering over listing... I just went from the first contact= first chance. 5 people set up an appt to come see/buy it and no call/no showed. I was astounded by people's manners.
This is, very unfortunately, the way a majority people behave these days. Especially younger individuals. I experience it on nearly a daily basis. The business-world has become rampant with no calls, no shows, no follow ups, no manners and no people with integrity. It's to a point that a term has been adopted for it. Ghosted and ghosting have become standard operation procedure. There are a plethora of reasons which I could go on about ad infinitum. Suffice it to say, as previously mentioned, complete lack of integrity.
