Discontinued in 2005, the Deville and its technology and prestige were synonymous with Cadillac. More recent models offered convenience technologies that stood above the commonplace, such as tri-zone climate control that allowed the driver and front passenger to choose their own temperature range, plus a third zone that put rear heat and air conditioning in control of those in back. Its 4.6L Northstar V8 featured an electronically controlled ignition to optimize combustion and power. And the Deville’s four-wheel independent suspension included control arms made of aircraft-type aluminum. To locate Deville parts, contact your Cadillac dealer.
