$0 Down $48 a week!! The Cadillac CTS receives only minor trim and package revisions for 2006. Most significantly, theres a new 18-inch performance tire-and-wheel package available for 3.6-liter V6-equipped cars. Like the 17-inch wheel package it includes HID headlights, a sport-tuned suspension, and stability control, but also has a tire-pressure monitoring system and stronger brakes. As the first Cadillac car to employ the companys new design philosophy, the CTS is a bold step forward for a division that is trying to regain its status as a top-tier luxury carmaker. Cadillac is hoping to attract customers by offering sport sedan performance combined with the room and comfort of a midsize vehicle. The Cadillac CTS offers standard four-wheel antilock disc brakes, traction control, seat-mounted side airbags for front occupants and side curtain airbags that protect both front and rear passengers; stability control is optional.
