It's not hard to get a parking permit for your car, but you might not get your first choice of lot. The costs for parking aren't too bad, but having a car on campus isn't all that necessary. Lots of students have bikes or just walk places. Nothing is very far away from campus. Plus, if you do need to go farther, it is likely that you will meet and become friends with someone who does have a car on campus. At least for your first year, it would probably be a good idea to leave the car at home for several reasons. First, you won't be tempted to run home every weekend because you're a little homesick. It will make you stay on campus and get involved. Second, it's just less of a hassle. You don't have to worry about paying for gas, and when it snows, you won't have to shovel out your car. And lastly, you don't have to pay for a permit, and there is absolutely no way that you'll get a ticket if you don't even have a car on campus.
Parking is pretty well enforced. While tickets aren't that much, they do add up. Some people might say that they've parked in the wrong lot overnight and not gotten a ticket, but they're lucky. Lots of people test their luck twice and get busted for it. So be smart and get a parking permit, and park in your assigned lot.
