2016 Buick LaCrosse Ultra Luxury Package Package With Navigation $15,990

As Buick's flagship sedan, the 2016 Buick LaCrosse offers the generous size and accommodations traditionally associated with the brand. Passenger space is copious, with rear legroom rivaling that of some executive-class luxury sedans. Pleasingly, the LaCrosse isn't a snooze to drive either, which you might otherwise assume given the brand's history. That said, only one of the two engines available is truly suitable for this class of car. There's either a capable 304-horsepower V6 or a mild-hybrid four-cylinder unit dubbed eAssist. While the latter option provides better fuel economy, we're not convinced it's worth sacrificing the V6's additional power or available all-wheel-drive system. Regardless of what's under the hood, every LaCrosse is stylish and well-equipped. For 2016, the LaCrosse's IntelliLink infotainment system gets some notable updates, including a revised touchscreen interface, dual USB ports and advanced smartphone integration courtesy of Apple CarPlay and Android Auto compatibility.
