Maybe the seller does have a more altruistic intent. I'm not defending him as I don't know him, he may actually want $10,000 for it. OR.... it's on FBM, which needs a price, and we've all seen ads for items for $1, or $123,456 or whatever. IF the seller really does have a reasonable price in mind, say $500 or $1000 or whatever, he isn't going to list that price because he'd have a hundred phone calls from other guys looking to buy it and track down the current owner and sell if for far more. At $10k, it cuts out all the BS.
