The Encore I picked up has what they call the Convenience package, its the model in the middle, but it does have features that my LT Trax didn't have.
It has a power seats, 18" wheels bigger tires, and a quiet package, climatic Air Cond, a way nicer instrument panel with a heat gauge.
A nicer radio with more speakers with all kinds of apps such as weather and traffic information.
It doesn't have a sunroof, I avoid those because of the cost plus they always leak,
I can attest to the quiet package this Encore is more quiet than my Trax was.
On my Trax I could hear the road surface echoing through the suspension, when on rough pavement the Buick is very quiet
