Took 2 weeks and headed to Vermont to get away from the Texas heat. My 2017 GT premium with PP performed flawlessly. My overall mileage was 4255 round trip and I averaged 24.9 miles per gal. For most of the trip we used major highways where I could set the cruise on 80 mph, cover lots of ground quick. The GPS/sync3 make traveling easy and fun. Everything was a voice command away. Gas and hotels were easy to find. No matter where we stopped, gas, food, hotel we always got complements on the Mustang. I've had a number of mustangs and this one is hands down the best one.
