I'm selling the 2011 MacBook Air 13.3" base model.
Here's a link to the CL add:

Includes original box, charger, documentations and a sleeve to carry it in. MS Office 2011 can be installed as well. Warranty ends in late July, but you can add AppleCare if you'd like before the warranty expires.
Asking $975 plus shipping or local pickup in San Francisco. I can ship within the U.S.
