Owner of MY 2014 Corolla @85k Miles

Hi all,

I have owned my car (I bought it new in Aug 2014) for almost five years and I wanted some advice on whether or not I should take in my car for preventative maintenance. I was advised that I should only take in my car if something is wrong but I wanted to hear everyone's thoughts. And if I should take my car in for PM, how should I go about finding a dealer?

All advice is appreciated!
