I am hoping to buy a Prius within the next few months. I noticed a few responses from people who live in mountaineous regions like Colorado and Nevada, who seem to make it up hills okay. I also live in the 'wild, wild west' and am wondering how the Prius responds in mountain driving... REGARDLESS of snow... and in passing... and at high altitudes. I currently drive a New Beetle turbo and have always been very happy with its 'zip.' My dad used to drive a diesel Mercedes and its slow response drove me crazy... besides being risky in city traffic! Will appreciate any experience with this type of driving.
