What's New for 2002 For 2002, the DeVille gets a host of minor refinements, many of which won't be available until later in the year. New shocks and strut valving have been added to shore up the ride quality, leather seating is standard on all models and an optional advanced navigation system with voice-recognition capabilities is offered. A Bose 4.0 sound system can now be ordered, while digital satellite radio provisions will be available later in the year. Dual-stage airbag inflators, an increased oil change interval and a new wreath and crest Cadillac badge round out the rest of this year's changes.
