We had an 01 Oddity. Great vehicle, though we traded it in a long time ago because we needed something that can tow more. Because of that van though, my moms sister got a 2006ish Oddity. And their niece, a 2007ish Oddity. The one is still around with 200k miles of abuse. The other was replaced with a brand new Oddity after about 180k miles of abuse.
Oddity's are really, really fucking nice. The only issue is the transmission. That may have been fixed at some point, I'm really not sure.
Sienna's... Eh, they're really good, but not as good as the Honduh. Or at least that is what my brother told me back when he was selling Toyota's.
I'd also be shopping the Hyundai and Kia variants.
Now, for the last one. a Caravan/Grand Caravan/Town and Country/Routan. Seriously, these may not have quite the build quality, but the features are probably better than the others--swivel seats, stow-and-go, etc. And the price new is unbeatable.
