We have had our GT since August 20 and left for a road trip from Naples, Fl Sept 8, to Yankton, SD, and now in Denver, working back through the Dakota's and will head back to Florida after Thanksgiving. Just went over 5000 miles at the beginning of this week and had the oil changed at a Mazda dealer in Longmont, CO yesterday. I am very satisfied with this vehicle. As far as power, it has no problem passing or going up hills in higher altitudes. The GT 8 way seat is comfortable, and I have a bad back. The padding is stiff, however it conforms and have no complaints. The braking in an extreme condition is excellent, I can attest to that, because I unfortunately hit a deer, the deer came from the left, I hit the brakes at 65 mph, the deer was in front of me, the car stopped straight and true, it hit the deer's butt with the right front quarter, we were lucky. The car was repaired in 3 business days and back on the road. Car and Driver did a compare with this and 5 other small suv's , the CX5 came out on top.
