Get a good alarm with a remote and glass sensors. Ignition kill switch, don't leave valuables in there, take off the cd player faceplate when you park it (and don't just hide it in your car)...there are a million things you can do. Try looking around H-T, they always have people getting their cars stolen and broken into over there, and I'm sure there are tons of threads that will help you out on ideas.
