Buick's history isn't exactly stuffed full of all-wheel-drive vehicles, but with the recent redesign of the LaCrosse, Buick added an AWD option. Opting for the CXL trim is the only way to get all-wheel-drive in a LaCrosse as the less expensive CX and more expensive CXS (with a 3.6L V-6) only come with front-wheel-drive.
AWD cost: $2175 (vs. CXL FWD)
City/Hwy MPG: 16/25
AWD penalty: 1 mpg city, 1 mpg hwy
