A step up in the full-size sedan offering from Buick is the 2006 Buick Lucerne CXL V6, where the L stands for luxury.  The engine designation signals the 197-hp, 3.8-liter V6 under the hood (as opposed to the CXL V8 trim).  A 4-speed automatic is the only available transmission.  The 2006 Lucerne CXL V6 comes with larger 17-inch alloy wheels than the base CX.  ABS brakes, a tire monitor, traction control, crash sensor, and dual front-side and curtain airbags are standard.

The 2006 Lucerne CXL V6 also adds a lot more features to the base CX.  In addition to full power features, a power driver's seat, OnStar, cruise control, and keyless entry, the CXL V6 offers leather upholstery, a 6-way power passenger seat, heated mirrors, rain-sensing wipers, dual-zone climate control, HomeLink garage opener, a leather-wrapped steering wheel, an auto-dimming rearview mirror, and MP3 compatibility.  Options are similar to the base CX (parking assist, sunroof, satellite radio, remote start), but the CXL also can have a navigation system, heated and cooled seats, and heated wiper fluid.  A luxurious, roomy, and quiet ride are the hallmarks of the 2006 Lucerne CXL V6.  Poor gas mileage, peeling paint, and a bland and plastic-looking interio are common gripes.
