The 2004 model year is one of transition for Cadillac Seville. In May 2003, Cadillac discontinues the STS model to make way for the all-new Sigma-architecture based 2005 STS performance sedan, which begins production in summer 2004.
As a result, the only Cadillac Seville for the 2004 model year will be the SLS, which will be unchanged from the 2003 version and also will end production in December 2003. additionally, Cadillac will retire the Cadillac Seville nameplate after the SLS ends production.
The Cadillac Seville build-out strategy lays the foundation for a seamless release of the all-new STS, and is a key part of Cadillac's overall strategy to re-establish its luxury and performance credentials.
We've discontinued the STS for two primary reasons consistent with sphere demand, explained Susan Docherty, Cadillac Seville marketing manager. First, when a offering nears the end of its lifecycle, buyers tend to buy the lower-priced entry for the best value. The SLS is the best choice for those buyers. Second, our dealers asked us to simplify the model choices and available packages to help them clear inventories before the 2005 STS arrives.
