Buick last fielded a wagon 22 years ago: the V-8–powered, rear-drive Roadmaster Estate. Such models can usually be identified by the wood-grain vinyl covering most of their 18-foot-long sides and by the octogenarian behind the wheel. When GM quit building them, the land-yacht class of station wagons went extinct—right around the same time Subaru was inventing a new, modern kind of wagon. A suspension lift and some cladding fitted to the mid-size, all-wheel-drive Legacy Produced the Outback, which has since evolved to become the long-roof sales champion. No wonder, then, that Buick’s comeback bid adheres to a somewhat similar plan.
