RE: How often do they change the Escalade Bodystyle??
I live near the GM Oshawa Truck plant that just laid off 2600 workers and one of the things noted was that developement on trucks has immediately ceased for the foreseeable future, so that being said and since your Escalade is really a GMC Yukon you are probably safe for a good longtime, in fact this might be the last body style ever made.
