If your fleet needs the flexibility of a crossover with plenty of storage, be sure to put the Buick Enclave at the top of your list. The Enclave earned the 2013 Vincentric Best Fleet Value in America award with the lowest lifecycle costs in 15 of 20 scenarios measured, holding off the runner-up BMW X6. Depreciation, insurance, and better than average fuel costs were contributors to the Enclave’s win over other premium competitors.
