As we currently have a 2014 Cruze Diesel, one of the '17s was certainly under consideration for my vehicle before I decided on the Volt.
If the 2018s were out, and I could get the hatchback, as well as one trim level higher, I'd be in a Cruze Diesel hatch right now. But the '17s are only available in an LT sedan configuration.
Our '14 has been a great car, and easily surpasses the EPA mileage figures, especially once you put it on the freeway. We visited my in-laws last spring and made it from our house to Zebulon, NC (just east of Raleigh) without stopping. I filled the car up a couple days after arriving at 750 miles on the tank. And that was with the trunk absolutely packed.
