Buy Decision: '10 Cobalt vs. '13 Spark

I have to drive across the country to Montana in about a week and I have the decision for purchasing either a 2010 Chevy Cobalt 2dr w/ 60k miles or 2013 Chevy Spark w/ 19k miles. They'll both be the same price and are sold by a close friend who drives them to and from work to ensure reliability.

Since I'll be living there through the winter, I'm kind of concerned about a minicar in the snow. What do you guys think?
