The 2012 Buick Enclave is a large crossover SUV that's offered in four different trim levels. All have a standard seven-passenger seating configuration via second-row captain's chairs and a third-row bench seat. The base model is nicely equipped with 19-inch alloy wheels, bi-xenon headlights, foglamps, a power liftgate, heated outside mirrors, tri-zone automatic climate control and cloth upholstery. Other standard features include partial power front seats, a tilt-and-telescoping leather/wood steering wheel, keyless entry, cruise control, an auto-dimming rearview mirror, Bluetooth, OnStar and a six-speaker CD/MP3 audio system with an auxiliary audio jack and satellite radio. Stepping up to the Convenience Group trim level adds remote starting, rear parking assist and a rearview camera. The Leather Group tacks on leather upholstery, heated power front seats and driver memory settings.
