buying a 2014 pete 386

[putt putt]

I am flying out to look at it. What can be done on the lot? Gonna grab a oil sample and run it for sure. Is there a way to grab codes? I have no idea how these Def motors work. My tax situation is forcing this. I know what I am looking for as far as as brakes tires and all that. I know that it needs a overhead done because of the mileage and a egr tune up. My look on the guys lot is my biggest concern. It comes with the 2 yr encore warranty.
