I don't know I think an 07 would end up costing more than $500 over a 06. Nissan could raise their prices and dealers will be less likely to deal.

I probably just got the 06 because I'm impatient. The way I look at it I like everything about the 06, I don't feel it needs improvement, so why wait for the 07, when I could enjoy an 06 now and maybe save a little money. In the end it probably doesn't matter a whole lot, after the 07 ther will undoubtedly be an 08 which will probably be even better than the 07.
