Similar situation here, trading my lead foot 2020 with 29,000 miles, in for a 2023 Avalanche 5 over msrp. Its a 35 though, not the 37. Deposit yesterday, supposed to be in by the end of month. That would be a two week turnaround. Im nervous its gonna be a longer wait. I think having a desirable truck to trade in kinda puts those customers at the top of the list for these newer models for fast pick up. Yours doesn't happen to have the blue Recaro interior package does it? If so I would love to see it. Not sure what thats gonna look like.
