When Buick recently decided to name 11 "greatest hits" from its back catalog, it wanted one vehicle to define each decade the company has been making luxury cars. The most current model on the list and the one representing the modern Buick brand? The Enclave. This full-size crossover seats up to eight people in a giant interior that could also double as a moving van. Its luxury styling elements, quiet cabin and optional AWD have earned the V-6-powered Enclave not only prestige within Buick’s history, but also a breakout sales success rank that few expected when the model was launched as a 2008 model.
