With the elimination of the LaCrosse full-size sedan, Buick now finds itself with just a single car model. And unlike the U.S., Canada is not home to the Regal TourX wagon. What we have is the Regal Sportback and its smooth silhouette complete with a rear liftgate for extra versatility. Few rivals offer the same thing. Meanwhile, there’s a turbocharged four-cylinder producing 250 horsepower under the hood. Want more? Then consider the sporty Regal GS featuring a 310-horsepower V6.
