I've hauled a 24" prehung interior door several times in my 2011 Volt. I folded the rear seats down, and reclined the front passenger seat as far as it would go. The door then "draped" over what was left of the passenger seat sticking up. It was tight, so I would imagine a narrower vehicle wouldn't work so well; I wonder if the Bolt could do that (not that I ever want to have to do it again, but that's another story).
