The most important thing to consider when deciding to buy a car is how much you're going to use it. Obviously, if it's just going to sit outside your dorm or apartment for four years, it's not worth it. And if you find yourself driving alongside university buses all the time, car ownership may still not be a great idea.
Where is your school? Are you in the middle of nowhere, or are you in a city with public transportation?
How comprehensive are campus shuttles?
How many people on campus have cars? If the number is relatively small, you can probably get by with your student ID and walking shoes.
