Amazing Subcompact
Dee, 04/20/2022
2022 Buick Encore GX Essence 4dr SUV AWD (1.3L 3cyl Turbo 9A)
Great ride, loaded with features, dependable. Lots of pep (Essence model). Classy interior too. Downside is men would find the seat a bit narrow. If buying the GX spend a little more and get the Essence model with the bigger engine and 9 speed transmission.
