Large front lighting clusters and an eggcrate grille give DeVille a bold appearance. Turn-signal indicators are integrated into the side mirrors, alerting drivers alongside of your intention to turn or change lanes.

In profile the DeVille looks like a Cadillac. Large doors, massive body panels and expansive glass are broken only by trim along the lower body section. Large wheel wells are filled by 16-inch alloy wheels on DeVille and DHS, or 17-inch wheels and performance tires on DTS.

From the rear, the DeVille carries the traditional Cadillac ambiance, but with a far more contemporary flair. The fins of yesteryear may be gone, but those twin vertical slashes still shout Cadillac loud and clear. The tail lamps, redesigned for 2003, rely on Cadillac's industry-leading LED technology to light up significantly faster than normal incandescent units, giving drivers of following cars an extra fraction of a second warning, which is all it takes in some cases, to prevent a collision. The rear turn signals are distinctive and stand out brightly when blinking.
