Three days ago I listed a skid steer on FB Marketplace. Had a lot interest/questions. A female asked for my phone number because her FIL was interested. He called, showed up (60 mile drive one way) after a long conversation of every detail I could think of. He looks, starts, maneuvers around, ask more questions, starts it again, putts around a bit, looks some more. He then goes over to look at a couple of horses and tell me how he likes the black one!
Finally he say, "Let me think about it." as he and his buddy walk towards their truck. I told him I appreciate his time and interest, but if he thinks about it too long it may not be here. I told him the first one with the money will have it on their trailer. Oh, he says, "That's what I'd do to". He's a used car salesman with a farm, or so he told me. He just came to kick tires and find a machine at wholesale prices so he could make some money, I'm sure.
As I was walking to the house, I called the guy who had contacted me while I was waiting for this guy to show up. He was 40 miles away. He showed up in about 1 1/2 hrs with trailer. He went home with it.
It's not always the sellers who are questionable!!!
