Chevy Lumina

Please don`t burn me for asking this,but i thought 2003 was the last chevy lumina made.I even call the chevrolet company and told me that chevy luminas wasn`t selling good enough for them to keep them on the market.and she said that they will discontinue them after 2003.So where did the 2004 come from.i can`t even find them on the chevrolet website
