Front seats in the LaCrosse are nothing to grumble about—they're a bit soft but long-distance comfortable nevertheless. A wide range of materials, including plastic, wood and leather, with quality rising as you move up the model line—although the faux wood in some models feels a little out of place. Faux stitching on the dashboard and well-upholstered and bolstered seats make for a more luxurious setting than might be expected from the LaCrosse's mid-market pricing, and the top-level CXS gets upgraded perforated leather and ventilated heating and cooling features, along with more adjustability and memory settings.
Ride quality is impressive, and the interior is very well hushed from road and wind noise. There's only one nit: The 3.6-liter V-6 is a little raspy-sounding in this application and its character doesn't marry so well with the otherwise sophisticated and supremely muted and isolated feel of the car.
