I just bought a new Trail two weeks ago.
Crawl and Terrain Select, and the factory locking diff were the main reasons. Love the manual 4wd selection lever too. The wheels look much better to me too, and the hood scoop looks neat even though its fake.
I went with the non-premium, and like the color of the Trail seats better over the SR5's, as well as the dash color difference.
Additionally, the dealer didn't have any 4wd SR5's, and only the one Trail at a great price, so that made the choice easy.
