Too expensive for a worse vehicle than the Model Y (with incentives, it was a >$20K difference). I take 1-2 trips for 12 hours a year and the Buzz gets >100mi less range, so that's also a consideration. If it wasn't 50% heavier, it would probably get better range.

IIRC the first generation of it also didn't have the right plug to use the supercharger network, didn't have fast charging, or wasn't available >5 seats in the US, so we've kept waiting for future iterations to improve and it hasn't been good enough for the high price.
