After thinking about it, and the initial happiness wore off, I ended up paying bills (student loans and such) and upgrading some stuff, rather than getting a car, mainly for two reasons:
1) I could have only bought a car that was fairly cheap, and I was afraid it'd break down in a year or two and then I'd have been back where I started, since I wouldn't have been able to fix it. Even something fairly minor like needing to replace the tires to pass inspection could have been undoable. So I figured, why buy something that I won't be able to maintain for long?
2) It was just going to cost too much. I can buy a monthly bus pass for about the price of insurance for a car, plus then I don't have to pay for maintenance (oil, etc.), and especially gas. The only issue* with that plan is that I like in a semi-rural area, and the bus doesn't go on Sundays or at nights, so I'm limited as to where I can go and when (e.g. this morning my priest picked me up and drove me to liturgy).
Btw, I see now that I didn't respond to the last posts in this thread, I apologize for that. I did read your advice at the time.
* I sort of worked out getting to school, so that isn't an issue... until maybe next fall.
