Completely redesigned last year, Buick's three-row midsize SUV offers a selection of three models: the entry-level Preferred, the sportier ST and the more luxurious Avenir. The driver is greeted by a 30-inch display with Google built-in. All Enclave models excel in the comfort department and are powered by a turbocharged four-cylinder engine that delivers 328 horsepower along with excellent fuel economy. They can tow up to 5,000 lbs.
