Jake, what you need is video surveillance. There are tons of dash cams out there, just do some research and pick one.
You can go all out on some expensive system, or do what I did; $20 cheapo dash cams from HK. One points forward, one backward.
I don't drive the 986 to campus much, but when I do, the cameras are always rolling. The units I purchased have night vision, motion detect, still shots, 1080 HD video and tons of advanced functions like loop recording.
I like to think that the sight of cameras themselves are a deterrent, but who knows. I do know this; I haven't had a single problem since I started using them and I used to get little door dings and scratches all the time
