Is a Yaris right for me?

[Nihau]

Hello Yaris World!

So here's the deal: I just got a new job that will require a good deal of driving so I'm trying to find the right car. The fuel efficiency, styling and price of the Yaris really appeal to me. I also remember it being really peppy. I've liked Yaris' for awhile now, but I'm not sure its the right car. So please tell me if you think a Yaris would be good for me or if I should suck it up and buy a less efficient vehicle...

I live in Colorado and will spend most of the time driving in the Denver/ Boulder areas, but I will be driving to the Western Slope a couple times a month or less year round (so over 3 mountain passes, steep, curvy and just mountainous in general and snowy/ icy depending on the time of year about a 3 hour drive each way). Also I have an affection for time spent in the mountains which often includes hiking in new areas reached by dirt roads.

So that's it. Do you all think this is too much for a Yaris or would I be just fine? I'm used to a honda civic and it has been fine, but I also worry I'm abusing the car and should just buy a more mountain ready car.

Thanks Yaris World
