Sorry to hear about the damage. I would ask for a complete replacement. I don't know why you would need to replace the entire front end to color match. I can only imagine there would be a huge difference in color if your car wasn't a factory color or has some serious years on the car.

Also, Rallye is no better than Hassel. They take photos of your car when you drop it off with them so they are not liable for any damage that is pre-existing, but I have friends that have had similar problems with you. They will notice damage that was not there prior to dropping the car off and Rallye "fails" to inform you before you take the car. At least Hassel has been somewhat responsive with meeting your demands. Rallye has been trying to hold out for months from fixing my friends car.
