Thats just jacked up man!
When I sold my sport bike on craigslist I told everyone that called that I would do cash only and the exchange would have to be made inside a bank to verify the money was good.
Had a lot of people call that refused to do it! Always wanted me to meet them at some location that I wasnt familiar with. I wouldnt go, they would always say "well you must not want to sell it to bad!" Didnt have to sell so I wasnt worried about it. Finally a guy called, I explained how and where the exchange would be made he said no problem, he looked the bike over, walked in the bank, verified the money was good, walked out and loaded the bike and everyone left happy.
Hopefully you get your Banshee back and your next deal works out better for you. Do it on your terms! If they want it bad enough and have nothing to hide they will come. GLWS!
