Among the original trio of GM’s Lambda crossover SUVs, the Buick Enclave is the most luxurious and demands the highest base MSRP. The Enclave comes standard with a direct-injected V-6 and is offered in either front- or four-wheel drive. With seating for up to seven passengers and a 4,500-pound maximum towing capacity, the Enclave can handle the duties of a full-size SUV with the fuel efficiency of a smaller crossover. The Buick Enclave comes with a five-year/100,000-mile powertrain warranty and gets an estimated 22-24 mpg on the highway.
