I don’t know which car is safer in the long run. Thoughts?

What is your question?

So, currently, nothing is wrong with my car. However, I am searching for assistance with a slightly weird question. I have two cars: a 2015 Kia Soul and a 2014 Chevy Cruze. Both have about 100,000 miles. Both used. Both are in good working condition. I need to sell one of them, but I am a single woman with zero car knowledge, and I don’t know which would be more prudent to keep, which would last longer for me. The Cruze has had a host of new parts out on, the previous owner took good care of it, but it needed new spark plugs, spark-plug coils, tires, and a pipe (I believe he called it a PCV pipe, but I’m not entirely certain). It has never given me any issues except for these mechanical ones. The Soul has never needed any new parts. However, I travel a lot, and the Soul is less convenient space-wise. It also feels less safe, as the Cruze feels more solid and seems to get better MPG. Just looking for some advice on the matter!
