Nissan just finished up their "Tent Sale" pushing Maximas, Altimas, Rogues and Muranos. Z's probably weren't on the priority list. You may find yourself getting callbacks this week.
FWIW, I was in Boardwalk Nissan (supporting dealer located in CA) on Friday and they have a Solid Red base + Sport 6MT. Mike's pricing is more than fair.
