The Buick Enclave, the posh version of the Chevrolet Traverse/GMC Acadia tandem, remains the same for 2015. This ultra-roomy crossover seats seven passengers very comfortably. In back, there’s a vast 660L cargo capacity that increases up to 3,263 litres once the backseats are lowered. Under the hood, you’ll find the popular 3.6L 288-hp V6 paired with a six-speed automatic transmission. AWD is optional.
