I have a MBP that is about 1 year old with applecare and at the time the top of the line. I need a special configured one for an online course I am teaching so I am in the process of wondering how to sell this MacBook Pro. Never sold a computer online, but if you are interested I can give you all the scoop, and if you and I can agree on a price and how neither of us can get ripped off, I will then have to find out how to wipe out the hard drive.
The Applecare can be transferred to the new owner, I purchased it at the local Apple Store, and I am sure you can look up the serial number on Apple's website. I looked up the serial number for kicks on a website that is not related to Apple lie www.MacBookproserialnumber.com or something like that. It gave everything correct except the upgrade I did from a 2..06 processor to a 3.06 or something close to this. That is the only error I could find.
I know it has 8gb RAM, 500 GB hardrive, 7200rpm, I doubt I can afford to go lower than $1400 if I want to make. New, it was $2200 without the applecare.
