The 2007 Buick Lucerne is neither an all-star nor a bench warmer. For those who insist on American-made vehicles, this family sedan is a decent enough choice, offering some power and interesting handling capabilities on the top level trim, the CXS. But inconsistent build quality and the lack of leadership in any particular category that buyers in this segment value cause the Lucerne to be a competent but not outstanding entry. There are a number of vehicles to choose from in this busy segment, and the Lucerne is a decent enough car, but there are so many choices and some of those choices are much better options for reasonably-priced luxury sedan cars.

For 2007, the Buick Lucerne gets a few minor changes, including a heated steering wheel, an upgraded version of OnStar and a few new color schemes. GM has also extended the powertrain warranty on all of its models to five years or 100,000 miles.
The 2007 Buick Lucerne large sedan is available in three trim levels: CX, CXL, and CXS. The CX starts off with 16-inch alloy wheels, while the CXL adds 17-inch alloy wheels, heated outside mirrors, rain-sensing wipers, and optional heated windshield washer fluid. The CXS comes with 18-inch alloy wheels and Buick's MRC suspension. Optional on all trims are a moonroof and rear park assist.
The Lucerne actually offers some interesting body lines and a nice appearance with some style. While Buick isn’t typically a front-runner in the most stylish vehicle category, the Lucerne manages something of an eye-catching appearance.
The CX has standard features that include full power accessories, keyless entry, a power driver seat, OnStar telematics, a CD player, and steering-wheel-mounted audio controls. The CXL adds leather upholstery, an auto-dimming rearview mirror, dual-zone automatic climate control, and an MP3-capable stereo with an auxiliary audio jack. Optional for the CXL trim are heated and cooled seats. The premier trim CXS then adds driver-seat memory, heated front seats, satellite radio, a 280-watt Harman Kardon audio system, and a heated steering wheel. Available for the CXL and CXS trims are heated and cooled seats and a navigation system. Optional for all models are a CD changer and remote vehicle-starting.
With an uncluttered style and easy-to-use controls, the Lucerne’s cabin is rather nice for its price range. The interior is spacious and comfortable. Unfortunately, the build quality is inconsistent throughout the cabin, and the materials also vary in quality. While the interior meets comfort and space standards with a respectable amount of features, the quality inconsistencies are noticeable and leave the cabin lacking when compared to some rivals.
Performance & Handling
The CX and CXL use a 3.8-liter V-6 that provides 197 horsepower and 227 lb-ft of torque. Available on the CXL and standard on the CXS is a 4.6-liter V-8 rated at 275 hp and 290 lb-ft of torque. All models are front-wheel drive with a four-speed automatic transmission. Tests of the V-8-equipped CXL turned out a zero-to-60-mph time of 7.7 seconds. The Lucerne is neither a snail nor a speedster, finding itself in the middle of the pack in this segment power-wise.
Handling is divided into two groups: the subpar CX and CXL trims with wobbly steering and noticeable body roll. The CXS has solid steering and surprisingly nimble maneuvering. While all models are the same with a quiet, comfortable, and pleasantly calm ride, upgrading to the CXS trim will have a dramatic impact on the handling.
Standard safety features for all models include anti-lock disc brakes, traction control, a tire-pressure monitor, front side-impact airbags and full-length, head-protecting side curtain airbags. Stability control and brake assist are standard on the CXS, optional for the CXL models and not available on CX trim. In NHTSA crash tests, the 2007 Buick Lucerne earned a five-star rating out of a possible five for its protection of the driver and front passenger in frontal impacts and four-star rating out of five for side-impact protection of front and rear occupants. In IIHS tests, the Lucerne scored a highest rating of ""good"" in frontal-offset testing and the second highest rating of ""acceptable"" in the side-impact test.
