2012 PA 12

After kayak fishing a few years and now getting on bigger waters it is time to get a Hobie in my life to save my arms for fishing! I may buy a 2016 Outback, but if I find a nice used PA12 for the right price I would probably go that route. I have been scouring various for sale sites and have seen several 2012 - 2014 PA12 models come up for sale. From searching here and on other sites it looks like the 2012 PA 12 brought around most of the changes that are still current (flat hatch in front of seat, vantage seat, and steering controls on the sides of the hull). It also appears that the 2012 - 2014 PA12 models were pretty much the same. What changes have been made, besides the new skeg, H rails, and V2 GT Mirage drives since 2012 to 2015/2016?

There is a 2012 PA12 for sale very local to me that appears to be in excellent condition from the pictures. Were there any problematic areas or issues known to the 2012 PA12 models that I should check out? Any areas/items on the boat I should really look out for?
