So I'm looking to buy a 2011 13 inch MacBook Pro and was wondering what are some things I should look for to make sure it's a 2011 version and isn't stolen? They said that the box and everything is included with it and the specs are i5 processor, 500gb of ram, 4gb 2.4ghz intel hd graphics 3000. I'm trading him a 32 inch LCD Vizio 720p + $700 in exchange. Think that's a good deal? I don't think he has warranty and there is a little scratch on the side
