This mid-size sedan took over where the Buick Regal and Century left off. The 2007 Buick LaCrosse comes in three trims -- CX, CXL, and CXS. It wasn't changed much this year, having only been introduced in 2005. Some tweaks to the gauges, updated wood trim, and a now-standard tire pressure monitor are the major upgrades. A solid family car, the 2007 LaCrosse comes with a 3.8-liter, 200-hp V6 in both the CX and CXL. A newer and stronger 3.6-liter, DOHC V6 hits 240-hp in the CXS. All models come standard with a 4-speed electronically controlled auto tran. Well-tricked out, the LaCrosse offers a sturdier suspension, heavy-duty steel body parts, and more insulation to reduce road and engine noise, providing a quiet, comfortable ride. Base features are fairly extensive, including ABS brakes, traction, dual front and side impact airbags, OnStar, keyless entry, remote start, power driver's seat, and air conditioning. As you move up, you also get leather seats, dual zone climate control and a split-folding rear seat with fold-down armrest. The CXS goes for optimal handling and performance, with bigger anti-sway bars and 17-inch tires. The five-person sedan can also fit six if you get the optional bench seat for the front row. This features a center-folding backrest that doubles as an armrest or console. Though not a head-turner in terms of style, the 2007 LaCrosse offers a bit of luxury and practicality for the everyday commuter or family toter. Highlights include responsive handling, precise turning, a smooth and quiet ride, and good acceleration with the 3.6 engine.
