Let us know if you find one that carries it - it seems to be a big secretive thing for some reason. You'd think they would post a list of all dealerships that are carrying the plugin!
I called Honda Customer Service today, they didn't know, but offered to forward me to Honda corporate. They didn't know either (what dealerships might have them.) You might try calling Honda Customer Service as well. After a few calls they may put a list together.
I've called a couple dealers as well. One did quote me delivery for a factory order. They say ~3 months, but don't really have a date, from what I can tell.
Try Edmonds.com. It gives inventory on all available cars that you are looking for within a range from your zip code. I just hunted down mine this way.
