Almost ready to buy a 2017 Kia Niro Ex. We just came back from a trip to Denver Colorado and I was hoping to see other Niro's on the road but didn't see even one. That is from Henderson Nv. to Denver and back. My question was how it works in the mountains of Colorado (Vail and Loveland). The dealers here only have great things to say but they want to sell me a car. Does it have enough power to climb the passes and are you able to down shift to reduce speed downhill. Would appreciate your answers.
