Selling my old MacBook Pro laptop from 2011. Stopped using it in 2016, it's been on the shelf ever since. 
In 2016 I added the following:

SAMSUNG 850 EVO 500GB 2.5-Inch SATA III Internal SSD (MZ-75E500B/AM)

Crucial Technology 8GB Kit (4GBx2), 204-pin SODIMM, DDR3 PC3-10600

Everything worked great for years, only issue was the fan kept turning on, wasn't sure how to resolve this
Factory settings reset, back to original OS Lion install or whatever you want to load
Includes power cord
Lots of life left for someone who knows how to upgrade/maximize, enjoy!
