The LaCrosse debuted for 2005. Luxury features are plentiful, while attention to detail is solidly up to task. LaCrosse also handles soundly. Additionally, it has a quiet and comfortable ride, along with beautiful interior fit and finish. Overall though, it wasn't a significant leap forward from preceding Buick models. Rear seat room is tight and the base 3.8-liter V6 is thirsty and sounds coarse. The up-level 3.6-liter V6 is more refined. A 5.3-liter V8 lasted from 2008 until the 2010 redesign. Overall, this version of the LaCrosse scores well in our testing, though it slightly lags the class leaders.
