If your goal is to leverage the overall economy, then using the charge feature on the car will not be the way to go. As said above that will use more fuel energy then you gain in electric energy. It's really so you can feel cool driving quite up to someone's house after you depleted the range. You can certainly just drive it like another hybrid, the plug is is more of an added option than any sort of necessity. You also always have all power available, so the 400 rating is not limited to when you have a battery charge.

The CPO warranty is unlimited miles and does include the T8 battery, so not a bad way to go. I haven't seen any 100k cars yet, but they'll come. I believe time more than miles will be the limiting factor. I know there is a whole market for selling used batteries for the Prius that is much less expensive than buying a whole new battery for a 10 year old car. I imagine that market will continue to grow. I don't know for sure what differences in batteries there are between the Volvo models, but they are all the same platform... I wonder how interchangeable they are. Anyone have any ideas?
