Maybe he was just a crack dealer testing the waters?Remember, it only takes one.
I bet folks have thought this about things I've posted. I have a project Blazer out there for sale and got a message the other day that I was on crack and it was only worth 10% of what I am asking.
From my experience with people on crack, they tend to be delusional, but more of a paranoid, everyone is after me delusional which would make it unlikely for someone like that to be soliciting for people to call them about a vehicle.
