It's a Winner first and foremost, and second, one of the very very few almost fully in tune with an American sensibility ( and also certain International Sentiment ) that stretches back to the introduction of the 'Automobile'. And yes, they, meaning many most certainly do buy into all that because it is a Cadillac and how that fits in as well.
Sure, not all in the room want 'it' quite that way or even as a Cadillac with Cadillac flourishes and touches such as they are; GM knows this and provides the other answers still fully inline with that American sensibility referenced earlier. See Yukon Denali..... and the top trims and builds @ Chevrolet with Tahoe and Suburban.
Escalade is a bunch more normal - a bunch more American in flavor that a bunch of other Product out there, especially in less over congested areas.
