S8: 2014 vs 2015 vs 2016

[MCMLXIX]

It looks like the S8 got a face lift for 2015. What else changed between 2014 and 2015? If I were to start looking for an S8, is there an true advantage to get into a 2015?


And while they are still out of my price range, What changed for 2016 that the HP rating jumped from 520hp to 605hp?
Was it just different software or have they changed internals?


Also, CPO vs non-CPO?
If it's not CPO, what kind of warranty companies are out there?

For 2016, there is a S6 (520hp) and a S6 Plus (605hp). And, I don't know for sure, but prob just software.
