Getting its first use on Saturday, January 20, was a 2001Cadillac Deville Limousine, delivered recently to the white House for the Presidential Inaugural Parade for George W. Bush.

The new limousine has the exterior appearance of the 2001 Deville production models, with all-new construction under the skin. Handcrafted and dressed in a black clear coat finish, the limo is considerably longer, wider and taller than the production models. To maintain national security, the limo is equipped with state-of-the-art protection and communication systems.

Cadillac's Night Vision infrared-object-detection system is installed in the vehicle.

The vehicle interior boasts seven-passenger seating with improved comfort and visibility for all occupants. A rear-seat executive package featuring a concealed, foldaway desktop can be deployed when conducting affairs of state. The rear seats have an adjustable reclining feature and Cadillac adaptive-seat system for added comfort. Rear-seat passengers can enjoy their own premium sound system complete with a 10-disc CD changer.

"Cadillac is an Arnerican icon and we have had a long association with the U.S. government," said General Motors President and CEO Rick Wagoner. "Over six decades, we have served our country in a unique way by providing special vehicles and limousines for U.S. diplomats and foreign dignitaries."

One of the first chief executives to ride in a Cadillac was President Woodrow Wilson, who rode through the streets of Boston during a World War I victory parade. A lavish 1928 Cadillac town car was used extensively throughout the Coolidge administration.

President Eisenhower, known as a "car buff," rode in one of the first Eldorado's during the 1953 Inauguration Day Parade.
