Our early model awd Acadia now has a bit more than 6500 miles on it. We have yet to have it out on the open road so all our mileage is commuting to work and back and forth between our two homes. About 80% of our driving is at the 6500' level, but with only moderate stop and go driving. Our lowest mileage so far is 16 mpg with a high of 22 mpg. The average we have been getting is about 17 to 17.5 mpg. The car was delivered with only fair body panel fit, but excellent paint work. The interior seems to have been assembled well with no squeaks or rattles. We have had no mechanical problems, but have taken it back to the dealer for the recalls which the dealer handled promptly and had a list from GM of everthing that needed to be updated. The car has been driven on snow and ice and handled it very well. Driving the car on curvy mountain roads, it feels secure and safe, but I wouldn't call it sporty feeling. As far as the acceleration and passing power I would rate it average. The overall design of the vehicle is excellent. The interior is roomy and comfortable, fairly quiet, and very versatile, but GM needs to pay a little more attention to body panel fit.
