The Cadillac DeVille is one of America's best-selling full-size luxury cars.As you'd expect of Cadillac's flagship sedan, the DeVille coddles its occupants with a roomy, luxurious interior. The DeVille's powerful 4.6-liter V8 harmonizes with the smooth, responsive transmission, delivering quick acceleration and responsive passing performance.It feels solid and stable at high speeds, yet this big front-wheel-drive sedan offers surprisingly athletic handling, particularly the sporty DTS model. DeVille is mostly unchanged for 2004, though new heated and cooled front seats are available.
