Two small display screens on either side of the speedometer serve as the message center and compass. The system includes a redundant speedometer display, but no tachometer. The radio face has been replaced with larger and easier to use buttons and controls. Below the radio is the control center for the climate control system. Nothing is difficult to reach or understand, and there is so much available width that the controls are not crowded.

The Town Car's front and rear passenger compartments are very spacious. A new rear pillar design makes the rear seat cozier than the one in the old car. The big, thick seats are comfortable and the power front bucket seats offer lumbar support and two-position memory. The steering wheel contains buttons for cruise control and the sound system.

Interior noise has been reduced significantly over the previous model. The windshield has been moved forward four inches for improved aerodynamics. Rearview mirrors have been designed to generate much less wind noise. Thicker glass, triple seals on the doors, and redesigned pillars all help to further reduce noise.
