I saw a 2007 Cadillac Escalade driving northbound on Woodward today. It looked good, overall; it was nicely understated, and was free of the tacky fender flares of the previous model. But it did not have much of Cadillac's "Arts and Sciences" theme in it, which is a mistake. I think the Cadillac may look too much like the Chevrolet and GMC versions.
I don't understand the portholes. They are popping up on all kinds of cars (Buick, Land Rover), but they are non-functional and therefore silly.
Another styling element that I don't agree with on the new GM large SUVs is the line of the D pillar. Notice that the A, B, and C pillars all have round corners, but the D pillar has sharp angular corners.
