I need some advice about how much to sell my wife's 2011 MacBook Pro. It's an early 2011 MBP with a 2.3GHz i5, 320GB HDD and 4GB RAM. Last year she dropped it (still in her bag) and it left a dent near the optical drive. The drive works great and no other internals were damaged. I attached a pic. I did check on mac2sell and it listed the notebook for $910. I was thinking of listing my wife's machine for $700. Thoughts?
