What use case does a minivan solve that a VW ID BUZZ does not?

I guess it's technically not a minivan(?), but it's not very far from it!

Are the middle and rear seats in the ID Buzz storable or removable? That was the only thing I remember.

I would probably be ok with the abuzz, but you can't but it in the US yet.

It is the ideal form factor for anyone with a little bit of sense. It has the best room/capacity per footprint.

They aren't the most aerodynamic and had surprisingly bad fuel economy the last time I looked, but after those concerns it's hard to beat a minivan. I was shocked just how little cargo capacity my father in law's big fancy Mercedes SUV has - I was able to fit more in a Honda Fit (which explains the name!)

Don't think fuel economy is a real concern if you compare them to most SUVs.
