Selling Stolen(?) Items ebay.

So heres the deal, I was at my local gameshop, as I was leaving this guy yells at me. He says he has an Xbox 360 that he wants to sell, he says I can get it off him for $100. I figured he was a druggie or something and needed the money for crack or weed. Well I buy it, I figure I can sell it on ebay. The system works perfectly fine but.....The problem is I think it's stolen, there's no serial numbers or anything on it.

If I do sell this is there anyway they could track it?

try craigslist
do not give out your phone number
communicate with EMAIL ONLY
tell them you will meet them somewhere
if they insist on coming to your house, fuck them and move on to the next person
works, ive done it countless times
