I had the same thing happen on a motorcycle not to long ago. If you tell someone you're going to sell it to them unlist the thing. I card the guy about th bike he told me he would sell it to me for the agreed price and to call or text for the address an hour later after he got done eating. An hour later call him back (at this point I've got a rental truck to haul the bike as all I have is a different bike) and no answer no response to text msgs. No nothing.
And death climbs the steps one by one, To give you the rose that's been burnt by her son, Point me to the sky above I can't get there on my own, Walk me through the graveyard Dig up her bones
