I have a 13inch 2011 MBA with lion. The specs are - 1.7ghz i5 ; 4gb ram ; 256gb SSD ; OSX Lion ; Apple Care till Aug 2012. What would be a decent and fair price. I also don't have the box for the laptop, just the charger and laptop. The laptop ha been taken care pf really well, no scratches or scuffs or dents or anything to indicate that it is used.
