You are not buying for 3 years correct? I think more models will be added in the next three years than in the last 3. It is bordering on pointless to talk about today's models because it is likely none will be around in current form in 3 years. Perhaps the HAH and the Escape will remain unchanged, but the HCH an Insight will be all new for sure. The Prius in on the bubble. It is new enough that it may or may not be updated in 3 years.

None of the hybrids currently avaliable are apples to apples as I'm sure you already know. If you are replacing a van the logical choice would be the Escape. By considering the Insight you are clearly not looking for a replacement for the van, so it is hard to tell what you want.

I'm sure you already know all about the existing hybrids so what is your reason for asking the question? Why not a second HCH? Maybe a manual next time? You like your HCH do you not? I like mine but it really depends on what YOU want.
