How much for this junk 2001 CVT Insight ?

So can you even hypermile in a CVT Insight ?

[MetroMPG]

You can hypermile anything. But the CVT Insight mileage can't touch the 5-speed's potential.

I'm seeing conflicting reports about the CVT model that say it may not even have lean burn capability. (Makes sense since the CVT version had a different emissions label.)

One owner (Wayland of White Zombie fame) who had both Insight versions simultaneously said the 5-speed would get ~80 mpg (US) on the same route and at the same speeds where the CVT would get ~60 mpg. (see http://www.plasmaboyracing.com/blog/?p=124 )

MetroMPG has gotten some phenomenal mileage with his Insight minus the battery pack, but I'm assuming that is through lots of coasting.

Not from coasting. That was from "driving with load" on secondary highways (45-50 mph) with the goal of keeping it in lean burn as much as possible.
