First Drive: 2010 Buick LaCrosse I-4

2010 Buick LaCrosse I-4
Buick's latest LaCrosse is one of the new General Motors' best success stories. Sales of the nameplate have increased dramatically, and more than one-third of all buyers are new to the General Motors family. Better yet, transaction prices are up by a whopping $8500, despite the fact that sticker prices haven't significantly increased.

In the days of the old GM, we wouldn't expect much in the way of changes so soon - the LaCrosse debuted in June 2009 - but the born-again automaker seems to think there's always room for improvement. The first major addition, a four-cylinder engine, is already in production.
