DTS stands for DeVille Touring Sedan. The DTS was a mildly revised version of the eighth-generation DeVille, built from 2005 to May 2011 on GM's front-wheel-drive G platform. It seats five, or six with the optional front bench. Cadillac also supplied it as a coachbuilder chassis for limousines and hearses. The one we have is a 2006 DTS in Black Raven, with an automatic gearbox.
