The Buick LaCrosse is a premium midsize sedan. It's quiet and pleasant-mannered as we'd expect of a Buick, yet its steering is more precise than owners of previous Buicks might expect, and it turns into corners crisply, with little body lean. Its V6 engines offer good power, growling under acceleration, but motoring along smoothly and quietly on the freeway, and the transmission works flawlessly. Inside is a rich, high-quality cabin with attractive woodgrain trim, nicely presented instruments and controls, and leather seats with nice-looking gathered stitching.
