There were some changes occur for Cadillac in 1999. These changes include the introduction of massaging front seats that are available on d'Elegance and Concours models and the use of electronic suspension with StabiliTrak. Massaging front seats provide comfort to the riders. While electronic suspension is designed to aid control in fast turns by selectively applying the front brakes. The front brakes are standard on Concours and optional on others.

 

In the middle year of 1999, when DeVille celebrates its annual recognition, there was a Golden Anniversary option added to the car. The Option included special white paint, a wood interior trim, and a 2-tone leather upholstery. The car looks great and valuable, because its comfort, power and amenities are all superior as compared to the other cars. Cadillac DeVille's line was all new for the succeeding year 2000 model.
