My buddy here on the ship thinks that it might be a beat down scam where you show up with some cash and get jumped. I guess he heard about that happening a few times in the past. I've never bought anything off of craigslist myself and don't pay much attention to it.
due to the way its written I would say its stolen, has a hidden problem or like someone else said is a mugging waiting to happen. Don't those go for about $1800 new?
