I've heard that it will only come as a fully loaded truck, but it will still slot below the high country. That being said, I think somewhere between $60k and $65k sounds about right. The current high country with a 6.2 starts around $62K.The guys from GMuthority expect the ZR2 to start at 60K.
"With that in mind, it looks like around $60,000 would be the sweet spot for the 2022 Chevy Silverado ZR2 starting price point. "
In other place (I don't remember where) was saying ZR2 will not have too many options probably 1 package. If we can get it for 60K with all tech included ZR2 will be the BEST deal ever.
