@kingt Funny you mention that as the CX-30 is the car I've sorta kinda been ignoring throughout this process because of some of my annoyance at the bad packaging efficiency in her CX-5. The CX-5 is 173" long so same ballpark as everything here that's not the Kona, but interior volume is more like the Kona.
I've also been irritated by the fact that CX-30 makes you use a knob or voice input with Android Auto because there's no touchscreen. I do a lot of voice interacting with Android auto in my Civic Si but for simple stuff like flipping between nav & music I'd much rather she have the ability to do that in 1 screen tap vs. some knob twiddling.
But the more I looked at these 3.5 options (the Buick is only sorta kinda not really on the list) none of them feels like such a slam dunk that we shouldn't look at the CX-30.
