why wait? The 2016 absolutely fantastic, 100km/hr gets your 51mpg, and 95 km/hr gets you about 62mpg, which is 3.6litre/100km. The city is a lot less, can't seem to do better than 36, even if i drive like a turtle.
android auto is fantastic(but you have to take the password off your phone or you will have issues) the noise inside the cabin is only 68DB @ 100km/hr, its a joy
