The best you can do is try not to draw attention to your car, practice defensive parking (far away and not near other ding causing cars), and walk more around campus. I say keep your car clean, but don't go nuts cuz that's when people notice. Keep a low profile. Don't let everybody know that you have a system cuz college kids are all crooks.

Not that it would make it acceptable, but you drive an Accord, not an Aston Martin.
