I like Chrysler Neighborhood Care, they are close to me, and they never give up on a problem. Nobody is perfect, but they go the extra mile to make things right, and in the end, thats all you can ask from anyone. I had a strange, intermittant clunk that defied analysis, but they found it. Good people.
Another one is John Horton, West Coast Vipers. I think he is the only independant in So Cal that is authorized by the factory to do warranty work. Real sharp guy.
