When I was looking, the Sales Manager specifically told me that GM was no longer offering the Driver's Alert I package, Driver's Alert II package, or Technology package on anything other than a Denali. Those three packages are a requirement for me.
Trying to order an SLT or AT-4 (I wanted the AT-4) with those packages meant you would stay in purgatory for a long time.
He said the Denali 3.0L order would be accepted almost immediately since they are prioritizing the most expensive / profitable vehicles first.
I put down a $2,000 deposit and they said it would hit allocation in a few days. I got an order number.
We shall see. I'll update when I hear something else.
