As the largest sedan that Buick sells as of 2014, the LaCrosse has a very important role to fill. Buick has long been a brand associated with affordable luxury and refinement. If the biggest and best sedan it makes can’t make par, there is very little hope for the brand as a whole. When 2014 rolled around, Buick revealed a full-model refresh that had a more modern exterior design and improved interior ergonomics. Now for 2015, Buick looks to build on that platform by enhancing the list of available standard technology and features.
