If you've got an old cell phone you no longer use (but haven't thrown away / recycled), just tape it somewhere in the car and cover it with something so it's not obvious. Then connect it to your home wifi (assuming the car is parked closed to the house), and turn on a live streaming app like ustream / whatever. It'll burn through the phone battery pretty quick though, so you'll probably need to plug it in somehow. Wouldn't do much for motion detection or night vision, but might be an easy way to get started.
