Cadillac has disappointed us in the past with concepts like this that come time for production, look nothing like it.
I disagree. Cadillac has shown many concepts that become production. The Escala concept is applied to the XT4 and XT6, and updated on the CT6. The other previous concepts, such as the Elmiraj and Ciel, do appear on other Cadillacs. The Evoq is the ELR, and there are more than what I remember of all the Cadillacs since riding in my uncle's white convertible Fleetwood in 1956!
