What car to rent for driving from Salt Lake City to Yellowstone?

This sounds like a silly question but thought I'd ask anyways.



I'll be vacationing in the Salt Lake City and Yellowstone areas for about 10 days in September. The two of us will have only 2 suitcases. I estimate that we will drive about 1500 miles during our trip, so the car should be comfortable and easy to drive.



Given the altitude and perhaps mountainous driving should we rent a car with 6 cylinders (e.g. Chevy Impala) or will a 4 cylinder engine be adequate (Ford Focus)?What car to rent for driving from Salt Lake City to Yellowstone?
I wouldn't worry too much about getting a 6-cyl.



Do your homework and you should be able to find a really good deal on a reasonable car. A Ford Focus or Chevy Cobalt will be plenty comfy for two people and could save you a ton of $$$What car to rent for driving from Salt Lake City to Yellowstone?
a 4 cylinder would be fine, but you might want to get the midsize car for your wife - i've noticed that women tend to get antsy when in cars for a long time.
