Wasted my time and money to drive and meet him. Seller bailed for "personal reasons" and couldn't care less how it affected me. Avoid like the plague.

The possible buyer needs to state the truth.
I apologized for canceling the meeting I informed him a family emergency with one of the childern came up. I had also told him the gun would not be sold to anyone else. I also told him I would bring the firearm to him at the fist of the week. In the mean time I got told how he was going to post bad reviews. I am sorry for the inconvenience I was going to make it right but family comes first I will not be bullied.
So yes the sell is off.
