Didn't two people just get killed while driving an M3 or 3 series around USC.
Regardless, I'm sure it will be safe, plenty of affluent families/spoiled kids driving amazing cars, but why not unload the car for now and drive around care-free.
In general, campus parking can be hectic. I know parking at my school at night can be touchy, especially during sporting events or visitation events like spring tours or family weekends.
PS, be prepared to give your group members rides
