GM customer service has indicated 4 to 5 months before the Z51 constraint is lifted. For me, this is hugely disappointing. Especially considering they are taking away allocations for people who won't give up the Z51 option. That is, you just can't sit and wait it out. I understand why (it would basically kill production given everyone would just wait for the constraint to be lifted) but it is very, very poor customer relationship situation. I can guarantee other companies would not have this occur. If I were GM, I would be firing suppliers and cancelling contracts... period.
