The 2015 Buick LaCrosse remains a particularly stylish choice when it comes to the larger entry-premium sedans, as the Tri-shield brand continues to keep its current flagship sedan well-provisioned with today’s latest technologies. For the 2015 selling season, that includes adding a major connectivity upgrade from OnStar that will help the LaCrosse stand out even further from its rivals while complementing Buick benefits like a standard eAssist powertrain and a hushed cabin that fully braces QuietTuning design principles.
