Which models of Cadillac Escalades are the same body styles?

Does anyone know from which year to which year the Cadillac Escalade body styles are the same ie.: 2002-2006 etc...? I have no idea but would like to know from 1999 up 'til 2009? Thanks!|||The Escalde debuted in 1999 along with the GMC Denali. It was built in the original "Tahoe" body style in 99 %26amp; 2000. There was no 2001 Escalde. In 2002 the redesigned Escalade came out and was a hit and made a lot of money for GM (I own a 2002). This style contiuned until 2006. During this body style we got the EXT (Chevy Avalanche big brother) and the ESV (Suburban twin). In 2007 when the entire GM Large SUV line was redesigned, we received the current Escalade. It has been basically unchanged since 2007. Hope this helps.
