Actually, all those lines hint at scam, but this is the one line that positively incriminates it as a serious scam:
"if you are welling to buy it you will have to let me know before the auction close"
He will reply to you that you need to Money Order the money with the Buy It Now price. He ends the auction early OR if you bid, he ends the auction early. With a Money Order or Western Union, you have no recourse. And, since he will end the auction early if you simply bid or don't bid, feedback will never happen.
