I watch eBay a lot for deals on the Mopar things I need for my projects. Every now and then I see listings that are just ridiculously high priced. Like 50 times more than it should be. I used to think they were honest mistakes but more and more I think there are some people who are just in fantasyland.
Last year at Spring Fling, I sold some guy a $20 part and he talked me down to like $1-2 bucks. I finally agreed so he'd just leave. Later that night, I saw the exact part I sold him (right down to the marks and paint overspray) on eBay for $200. Naturally, I follow him now just for laughs. He still lists that part now and then for $200 along with other items that are listed at ten times what they are worth.
You gotta just laugh at stuff like this.
