Low inventory doesn't tell us much. If there are three on the lot and the manufacturer sent them last year, sales are slow. If there are three on the lot and twenty were dropped off today, sales are pretty brisk.

As a van person (grew up with an 1987 Aerostar, ordered a 2017 Pacifica in 2016 (sold to Carvana this year when I got engine trouble), bought an 1981 Vanagon recently that might move on its own power soon), the problem is Stow and Go is clearly awesome, but owning a Chrysler isn't. Having a hybrid would be nice for fuel efficiency, but Chrysler removes features in their hybrid (no power rear seats, no Stow and Go), Toyota doesn't even let you take the middle seats out in the Hybrid Sienna. Minivans that aren't flexible aren't really worth it IMHO. If Honda figured out how to fold the middle seats into the floor, I'd buy an Odyssey in minutes.

All the commercial small vans pulled out of the market too; I wanted to get a Ford Transit Connect, but they left, and the used market for them is weird: mostly 100k+ miles. Nissan NV left, Ram Promaster City; neither offered a passenger model. I think I left something out. Mercedes Metris is still in, I think, but it's very basic. I'd like something more on the basic end, but still with fold into the floor rear seats at least.
