Not only is DeVille Cadillac's bestseller by a three-to-one margin, it has also been America's best-selling luxury car for the past 13 years. Ahead of its time, the DeVille even offered airbags for the 1974, 75, and 76 model years. This classic Cadillac model comes designed to appeal to the full range of traditional luxury-car buyers. The 1999 DeVille adds another level of comfort with the availability of a massaging lumbar seat. A roller built into the driver's seat massages back muscles to help reduce driver fatigue.
