Completely redesigned last year, the Buick Enclave is back without any major changes for 2019. The American midsize SUV, which can accommodate up to seven passengers, is emphasizing luxury more than ever with a high-end variant known as the Avenir. Technology is also ubiquitous on board with a multitude of driving aides. All versions of the Enclave come with a 3.6-litre six-cylinder engine that generates 310 horsepower.
