Isn't a black Charger just the most sinister car in the world? Good choice for the fear factor. It reminds me of that film with the possessed Lincoln Mk.4 (i think it was a Mk 4) that kept chasing people. I can't remember the name of it, but the car wouldn't go into graveyards. It was weird anyway.
This story reminded me a little bit of a Tarantino film with all the realistic and sharp dialogue.
