HIO, no offense intended by what I said or what I'm about to say.
Whether I know you or not, I still think the right thing to do is to correct any out-of-order mistakes, even if it means taking back VINS. I can't help but think that folks who ordered in Jan/Feb and got April delivery dates and VINs knew they were getting a gift at the time. Anyone who spends any amount of time on this forum is well aware of the Sept/Oct orders that have been patiently waiting for 7 months so far. It seems pretty incredible to believe that everyone wouldn't see the inequity of 2011 orders getting filled before 2010 orders.
That said, I'm not totally convinced Nissan is going to do that. Some folks have said they will, but I have not seen anything definitive from Nissan to that effect. And I will also acknowledge that if a VIN was rescinded, it would indeed be a bitter pill to swallow.
Enjoy your Leaf -- whenever you get it.
