The 2007 Buick Lucerne, a full-size sedan, marked the final iteration of the Lucerne nameplate, which had been revived in 2006 after a 40-year hiatus. This generation of Lucerne, based on the W-body platform shared with the Chevrolet Impala and Pontiac Grand Prix, offered a comfortable and refined driving experience, targeting a market seeking a spacious and luxurious sedan without the hefty price tag of a luxury brand. It was available in three trim levels: the base model, the CX, and the premium CXL. These trims offered varying degrees of equipment and luxury features, with the CXL featuring leather upholstery, heated and cooled front seats, and a premium sound system. The Lucerne boasted a roomy interior with ample space for five passengers, with ample legroom and headroom in both the front and rear seats.

Under the hood, the 2007 Buick Lucerne was powered by a 3.8L V6 engine or a more powerful 4.6L V8 engine, both mated to a four-speed automatic transmission. While the V6 provided adequate power for everyday driving, the V8 offered a more spirited performance, making the Lucerne a capable highway cruiser. The suspension, tuned for comfort, offered a smooth and quiet ride, while the power steering provided a reassuringly light feel, making it easy to maneuver in tight spaces. The Lucerne's styling, while not particularly groundbreaking, featured a respectable and traditional design that emphasized comfort and elegance.
