My first Craigslist ad I sold a set of rims. They were five bolt 17" rims that looked like they were repainted Cadillac rims... a guy bought them from me and just flat out bought them without checking to see if they would fit. Turns out Durangos are six bolt rims, so he couldn't have gotten it more wrong.
But anyway, sold them for $550, and he texted me the next day asking if he could get his money back, claiming I ripped him off because apparently at some point in our meet I told him they would fit. Over the next few weeks he sent me threatening texts telling me he was going to find out where I live and kick my ass and he was "coming for his money" and all this bullstuff. I told my dad and we went to the police station and made a statement. The police literally called him and told him to knock it off lol.
