Hello, I'm ready to make my first Jeep purchase and I'm leaning toward waiting for the 2017 lighter weight Jeep with the new engine that gets 28 MPG. Does anyone know much about the new 2017? We have rented jeeps in colorado and LOVED taking the back roads!!! I don't want to wait, but I will be driving it a lot and the better gas mileage would be GREAT! Thanks
