Structural, suspension and brake system enhancements are made across the board. Base models get MagnaSteer variable effort steering, while the Eldorado Touring Coupe (ETC) receives a new Integrated Chassis Control System (ICCS) that includes stability enhancement and road texture detection. All Eldos have slightly revised stereo and climate controls, and the OnStar services package is a slick new option that can notify emergency personnel where your disabled car is located or can allow you to book dinner reservations from the driver seat.
