This seems to happen to us all the time in Central PA area. I can't tell you how many times I have had sellers on Craig's List do this over the past couple years. I think the thing that makes me the most crazy are the ones that think my gas is free and sell a machine when I am on the way to pick it up.
I really don't get it but I am getting to the point I really don't care anymore. With all the BS going on with this hobby over the past couple years I am getting ready to thin out the collection some and go back to doing something with cars again.
Crazy thing is when I post fully working machines, just shopped, boards repaired, etc for a couple hundred over what people are selling junk for I can't sell them. Right now I have 7 machines for sale in the $500 to $750 price range fully shopped and ready for a home gameroom and have not been able to sell even one of them. Most are listed for about $200 more than I paid for them broken & dirty - I just don't get it these days.
