I've already put 2500 miles in three weeks on my new Cruze and so far I am very happy with it. 1000 mile trip I averaged 52.7mpg. Around 42 mpg in mixed driving. Just added a roof rack and cargo basket and will recalculate on my upcoming trip. Two adults, a dog and luggage max out the carrying capacity of this small sedan. I'm hoping the add on doesn't impact my fuel mileage too much.
