I agree on the Prius C, but my dad's Jazz Hybrid feels pretty lively, more so than my own 2nd gen Insight.
When I bought that I had been looking for small diesel cars, but some test drives later (and reading some customer reports) I gave up on those.
We'll see whether the particulate filters are really necessary on all gas cars.
Honda managed to get the original Civic clean enough to not need a cat in California.
They may do likewise now.
The Insight was voted
cleanest car in 2011, based on its low emissions on anything but CO
2.
Even if it needs a filter, the less particles it puts in the longer that will last.
I trust Honda will do really well.
