Not sure what would have changed, but Big congrats on the new ride! I got a 2016 Crossroads plus and couldn't be happier. I nearly purchased a 2014 crossroads almost exactly the same (with a few more options) but the crappy dealership sold it out from under me after we made the deal. Setup to sign papers the next day, then got a call they sold it. Anyways, I'm happy now since I've got nearly full warranty with the 2016. Peace of mind I guess.
As far as ride goes, tires can make or brake the entire feeling you have for a car. If the tires are crappy, then the ride will be too. Something to consider. Being that it's certified, my guess is you won't need tires for a while but something to consider down the road.
