Single Room vs. A Car...Hmmmm?

I'm really looking forward to next school year, because I'll finally be out of this difficult living situation I'm in now (see previous post) and I'll be one year closer to graduating. And my parents said that hopefully they will either get me a car or pay for me to live in a single dorm room. Hmmm, that's a really hard decision!
Upsides to having a car: I can drive home any weekend I want to without having to make my mom drive up and get me (definitely going to take advantage of that); I can go out to eat more often (believe me, the dining hall gets old); I can get to off-campus events more easily/safely (especially in the winter); I can escape the dorms if I want to (which I probably will).
Upsides to having a single room: no annoying or rude roommate to deal with (like I am now); more like a home-away-from-home; won't smell (another roommate issue); can go to bed whenever I want (there are a lot of upsides to not having a roommate).
This is such a difficult decision that I'm glad I have a couple of months to decide. Well, I have at least til February, when next year's housing applications are due. Both options have their upsides (and pretty much no downsides, as far as I can tell) so it's a really tough thing to decide on. If I had a car, and ended up with an annoying roommate, I could go home every weekend or just spend most of my time elsewhere (Starbucks and the mall, maybe?). If I had a single room, the roommate thing would never be an issue but if I still missed my family, I couldn't go home whenever I wanted to. So I'm still not sure. Help!
