Hi, I plan on selling my 15" Macbook Pro mid-2009 but not sure what price I should place on it. The uni-body is in mint condition, no scratches or dents. I replaced the battery a couple months ago and the only thing that shows any signs of usage is the keyboard. If you were to look at this laptop, you wouldn't be able to tell the difference between it and a new one. The only reason why I want to sell it is because I think it's time for an upgrade lol. How much would you guys pay for it? Need some advice. Thanks in advance for your comments.
