Congrats on the "new" car! I purchased a 2016 EX-L just over a year ago. It has been a great vehicle and we actually like it more now than the day we bought it.
I can't really think of anything to be on the look out for. Probably the biggest surprise for me is that based upon how/where you drive it seems the oil change interval is longer than what I have typically experienced.
Enjoy the new wheels!
