Why would anyone in the overland community give the buyer grief for buying a rig before someone else? I know thats not what you said exactly but its obviously what your insinuating. I say congrats to the buyer for buying an awesome rig, if you do see him, just leave him alone and let him enjoy his vehicle.
I bet this is how it went down:
The seller told the buyer that he has interested parties for his asking price and that he can come and see it, then the buyer offered $10,000 more than the asking price, said he has cash on hand and wants to drive it home- no need for a down payments, and possibly wait for someone to get a loan, etc.. MotoMind was right, they are basically made of drama
