Hi i am considering buying a used 2.0 GHZ Core Duo MBP, with 512mb of ram and a 80gb hd for $800. The seller claims the notebook is only 8 months old. I have several questions i would like to ask you all. 1. If the notebook is in good condition, do you think $800 is a good price? 2. How can i verify the notebooks age and warranty status? 3. Any adice as for things to look for when i go take a look at it? 4. Any advice in general , when buying a used mac? Your help is greatly appreciated.
