Like a multi-carat ring paraded on the finger of an NBA wife, some things are just so damn shiny and flashy that they don't require a formal introduction. Whether due to overwhelming size or a high blinding factor, there's just no escaping the brilliance. This was the case with the 2007 Cadillac Escalade ESV and EXT models that were officially, yet unceremoniously, unveiled at the 2006 North American International Auto Show in Detroit. There was no press conference rally, no fireworks - the sharp new look, generous use of chrome, and lustrous black paint said all that needed to be said.
