Thanks for the help guys. I understand that usually the color is hard to match on a 16 year old car due to fade, but my car is white. It should not have faded so much that it is impossible to get a close match. The color on my door now is a cream color that makes it noticable across a parking lot. It is not just a small difference in tones.
I would normally be willing to give the shop a chance to fix their mistakes, but now that all the electrical problems have come into play and things like my airbags are potentially at risk, I want to have a mercedes dealer fix all problems henceforth as I don't trust this guy with my life. I will wait until Wednesday for a reply from Progressive and then see what they have to say.
I am sure that the airbag issue and the lack of a car alarm right now will pursuade them to help me out.
