Manufacturer's Suggested Retail Price (MSRP), also known as "sticker" price, is a recommended selling price that automakers give a new car that is above the invoice price paid by the dealer. It is a price that does not include any options that can be added to a particular car style. When shown as a range, the prices are starting MSRPs, without options, for multiple styles for that model.
This price range reflects for-sale prices on Cars.com for this particular make, model and year.
Best Bets get above-average mpg, class-average or better reliability, class-average or better crash-test ratings, and our recommendation.
These city and highway gas mileage estimates are for the model's standard trim configurations. Where there are optional features, packages or equipment that result in higher gas mileage, those fuel-economy estimates are not included here.

Vehicle Overview Considered an entry-luxury, front-wheel-drive full-size sedan, the Lucerne was introduced at the 2005 Chicago Auto Show as the first Buick passenger car in a decade with available V-8 power. The Lucerne is also the first Buick to offer Magnetic Ride Control, which comes standard on uplevel CXS trims.
For 2007, a chrome grille is optional on CXL and CXS models. Two new exterior colors — Light Quartz Metallic and Gold Mist Metallic — are offered, along with two new interior colors, Cocoa/Cashmere and Cocoa/Shale.
Buick emphasizes the QuietTuning of the Lucerne and other models, which the automaker claims will reduce or tune out unwanted wind, road and powertrain noise. Three trim levels are available: CX, CXL and CXS.
Exterior Front-end styling of the Lucerne features a new waterfall-style grille that uses thin vertical vanes and includes a chrome Buick tri-shield emblem. Polycarbonate headlight modules that taper into the front fenders flank the grille. The front fascia features split air intakes.
Freshly designed chrome portholes — machined and set high in each front fender — are reminiscent of those on historic Buicks. Lucerne CX and CXL models with V-6 power have three portholes on each side, while V-8 sedans get four portholes per side — a differentiating idea that reaches as far back as 1949.
A steep, 60-degree windshield leads into a roofline that flows into a 70-degree rear window. Horizontal taillamps with floating inner lenses wrap into the deck lid and are separated by a Buick tri-shield emblem. CXS models with V-8 power feature chrome-tipped dual exhaust pipes.
Buick promotes the Lucerne's snug body gaps and tight wheel-to-wheel well relationships. Chrome wheels are optional, and painted aluminum wheels hold 18-inch tires on the CXS sedan. The CX gets 16-inch aluminum wheels, and CXL models wear 17-inch rubber.
Built on a 115.5-inch wheelbase, the Lucerne measures 204 inches long overall, stands 58 inches tall and is 74 inches wide. Options include rain-sensing wipers and heated windshield-washer fluid.
Interior Seating for either five or six occupants is available. The upholstery features French seams and stitching. Second-row legroom can be as much as 41 inches, courtesy of the Lucerne's long wheelbase. Second-row knee clearance is 5.5 inches, and the trunk holds 17 cubic feet of cargo.
Lucernes can be equipped with a touch-screen DVD-based navigation system, XM Satellite Radio, a 280-watt nine-speaker audio system, a heated leather-wrapped steering wheel, heated and cooled front seats, a remote starter and General Motors' OnStar Directions and Connections service.
Under the Hood The Lucerne is available with one of two engines. In the CX or CXL, the 3.8-liter V-6 meets Super Ultra Low Emissions Vehicle standards and produces an estimated 197 horsepower at 5,200 rpm and 227 pounds-feet of torque. Standard in the CXS and optional in the CXL, the 32-valve dual overhead cam all-aluminum 4.6-liter V-8 delivers an estimated 275 hp at 5,600 rpm and 295 pounds-feet of torque. Both engines work with a four-speed automatic transmission, run on regular-grade gasoline and feature electronic throttle control.
Safety Six airbags are standard in all Lucernes: a dual-stage driver's airbag, a dual-depth front passenger airbag, and side-impact and side curtain airbags. Options include all-disc antilock brakes with traction control, Ultrasonic Rear Parking Assist and GM's StabiliTrak electronic stability system.
