Bennelson have you actually read up on Honda's IMA system? It's much more simple (elegant?) than Toyota's system. The drivetrain is pretty standard Honda fare except for the electric motor which takes the place of the flywheel. Of course the systems that manage the battery and electric motor are foreign to other vehicles, but they're also solid state & shouldn't require much upkeep.
Then again, compared to your beater and Insight would seem like a fragile piece of crystal
Budomove... Don't do it :-p
