I went to a private school and my car (not a BMW but still nice) was fine the whole time. I went to grad school at Iowa and I NEVER used a car, it was all motorcycle from there out. A lot of people get scooters too (I wouldn't).
Just because your school doesn't offer parking you can usually find a spot to rent that is close to where you live, I rent a garage right now that is close to where I live because my apartment doesn't have indoor parking.
