100% agree on the diesel as the only viable option and yes that reduces the available inventory to nearly nothing at all. I want a Yukon XL Denali Reserve 3.0L diesel. I don't think there are any at a dealership in the US right now.I was in the same boat i.e. Denali, you have to check a lot of options to get adaptive cruise control for some reason. Additionally I will only go GM if I can get the diesel so my build chances are slim. Got an order for a Denali (tbd) and Escalade (eta 18 months originally, now 3 months later and still waiting). GM is strange that they don't add allocation for customer orders so you benefit by finding the largest volume SUV dealer to grab one of their allocations. Also means many of them are charging market adjustment or not committing to pricing since they have a fixed allocation.
