Buick has made choosing a 2006 Lucerne easy work, thanks to three clearly-defined trim levels and the availability of both V6 and V8 engines. Entry-level buyers will be interested in the Lucerne CX, with a starting price of $26,990 (including a $725 destination charge). The CX may be the least expensive Lucerne, but it comes with a long list of standard convenience and safety features. Among them are cruise control, a V6 engine, a trip computer, OnStar telematics, a CD player, a power driver’s seat, antilock brakes, and front-side and side-curtain airbags. Serving to dress up the CX a bit more is a Comfort and Convenience Package offering rain-sensing windshield wipers and heated mirrors; a Driver Confidence Package features rear park assist, an anti-theft alarm, and a remote starting system. Also on the options list is a Harmon Kardon sound system with an MP3 player, a power sunroof, and a front split bench seat that increases seating capacity from five to six.
