Thanks for the quick reply! Didn't realize I was being so vague. Here's some more detail:
It's just me and my two-year-old so I need a car that I would feel comfortable driving him around in. I ride my bike to work every day, so I drive less than 300 miles per month. Fuel efficiency would be nice, but I don't drive enough for it to make much of a difference. Most of my trips are only a few miles, but about once a month I'll go see my parents about 100 miles away. That involves driving over mountains, and through snow in the winter months, so it would need to be able to handle that. I don't tow anything and it doesn't need to hold bikes or canoes or any equipment like that.
I just need a simple car that's relatively safe, that'll handle the occasional grocery store trip and a monthly trip over the mountain.
