I am finding that there are many dealers in Texas with multiple Leafs (SL models I am looking at) on their lots and I called about and all but 1 are considered "Demos" which they have had in inventory for at least 6 months. Are there any issues with buying one of these 2011 Demo's? I am finding most to have under 200 miles. They have just been holding them and using one as the "test drive" one, as it was explained to me. I am seeing discounts on these by as much as $2200. Do these even qualify for the Tax credit?
