Never underestimate the value of a good dash cam. I was rear ended by a Tundra in my GC impreza and the driver denied she did any damage (which she did) and then took off. I never got her plate number and the police said I was basically screwed. Lesson learned! I now run a dash cam in my car. Next time I'll not only get the driver on film, but I'll also get a fun youtube video to share :)
