I have for sale a Mid 2012 Apple Macbook Pro 13" 2.5Ghz, 500gb hd, 4gb ram. It is upgradeable.

I can switch the hard drive to a 128GB SSD if you like as an option (it drastically makes things faster at the cost of space). Geekbench score with SSD is nearly identical to my Late 2013 MBP retina.

Downsides: dings, scratches, etc. I can take pictures for serious buyers.

I would rate condition as acceptable/good.
