Ok so I know this is a longshot, but previous answers to this question are several years old and I'm hoping things might have changed.
I just got a 2017 Bolt that popped up in a nearby dealership. It's in great condition and I'm loving it. Except there's one problem: once I got home I realized it didn't have DC fast charging. I didn't realize that was an upgrade so hadn't even checked. I know in the past people have said that it was a factory upgrade only, but I'm hoping that maybe there's been some progress with an aftermarket option.
Not a huge deal if not; I drive so little that even overnight Level 1 charging is enough to keep it full, but having the fast charge is kind of like peace of mind in case I ever do use the car's extended range.
