All GM small crossover / hatchbacks look similar, especially from behind. When I first bought the Bolt, I kept doing double-takes to see if a car was a Bolt. Besides the Buicks, the Trax and even the Equinox at a quick glance can look similar.
Ultimately, it's the rake of the Bolt's windshield (2017-21) that sets it apart more than anything else.
