I bought this vehicle after I read 50 reviews and some test drives. Other folks have done a great job of describing the joys of an Enclave. I have experienced mileage as high as 28 on flat road 55mph and no traffic. Typical on interstate at 70 is 23-24 if you keep your foot steady. 2 complaints- tires extremely noisy on some roads. I drive with both feet and periodically, if my foot is resting on the brake when I accelerate, the vehicle jumps. Have had a couple close calls. I now make sure my foot is off the brake. Dealer says my brake foot is confusing the throttle computer causing it to feed in more gas. One Toyota has same problem.
Quieter tires- check out brake throttle problem because this is dangerous
