It's been several years since General Motors had a minivan in the lineup, but the Buick Enclave and Chevrolet Traverse duo fill this role wonderfully even without the advantage of sliding side doors. The Enclave has a leg up on the Traverse in terms of luxury, but both are equipped with a 288-horsepower, 3.6-litre V6 and a six-speed automatic gearbox. Front-wheel drive comes standard, although all-wheel drive is available if you’re willing to shell out a few extra bucks.
