Subaru Dealer Holds Car Hostage After Facebook-Stalking The Owner

While I despise what the dealership has done in this situation (especially the part about billing her $1,200 for non-warranty repairs that she didn't authorize), I'm not really sure what she expected after posting pictures of her autocrossing a car that is still under warranty.  

She’s a software engineer, but does a lot with her car as a hobby, even beyond what most people do: she sells merchandise related to her car and her brand, she models with the car for photoshoots, and she actually drives the car as a sports car should be driven, doing autocrosses and other track events.
