Both cars were bought used. Did not receive the tax rebate on either of them. I put 09 altima wheels on the leaf. Kept the oem michelin tires. The center caps stuck out just a tad bit too much, wouldnt go in, so i installed 5mm hubcentric spacers on the front wheels. I havent heard anything about the 16 and 17 leaf packs, in fact i heard the opposite, that the 2014 and up had the lizard packs and the 11, 12 and some 13s suffered pretty serious battery degredation.
