Buy a used Buick Enclave or more recent models, and people may stop in the middle of the road to take a glance at your ride. The lavish design and unbelievably comfortable interior of the Buick Enclave has had people cooing over it since it was released. The 3.6 liter V6 engine mated to a six speed automatic transmission sends this car to staggering speeds very easily. Its large carrying capacity makes it the best used SUV Canada residents seek out.
